The movable panel is placed on the upper surface of the floor so as to close the opening of the floor.

Japanese Patent Publication No. 6-52225

In the composite environmental test apparatus disclosed in Patent Document 1, since the movable panel is placed on the upper surface of the floor, a step is generated at the edge portion of the movable panel. When there is such a step, it is necessary to install a member for filling the step (for example, a slope for filling the step).
An object of the present invention is to facilitate movement of a test object in a test apparatus.

Hereinafter, a plurality of modes will be described as means for solving the problems. These aspects can be arbitrarily combined as necessary.
A test apparatus according to an aspect of the present invention is a test apparatus that performs a test by vibrating or running a test object, and includes a fixed floor, a test execution unit, a movable panel, a floor surface member, and a plurality of loads. A receiving jig. The fixed floor is provided with a missing portion. The test execution unit is arranged corresponding to the missing portion and executes the test of the test object. The moving panel is installed below the fixed floor and can move in the horizontal direction as the test execution unit moves. The floor surface member is arranged on the fixed floor so as to cover the missing portion, and moves in the horizontal direction in accordance with the movement of the moving panel in a state where the missing portion of the fixed floor is covered. The plurality of load receiving jigs are disposed on the movable panel in the missing portion. Further, the load receiving jig receives the load from the floor surface member together with the movable panel at least when the test object is on the floor surface member.

In the above test apparatus, first, the test execution unit is moved to a predetermined position corresponding to the test object. As the test execution unit moves, the moving panel moves in the horizontal direction. Then, the test object is moved to the arrangement position of the test execution unit through the floor table surface material from the fixed bed. Thereafter, various tests are started by the test execution unit.

  In the above test apparatus, a load receiving jig is arranged in a missing portion of the fixed floor, and the load receiving jig receives a load from the floor surface member together with the movable panel when the test object is on the floor surface member. . As a result, when the test object passes over the floor surface member, the floor surface member does not bend greatly even if the thickness of the floor surface member is as thin as a predetermined value or less and its rigidity is low. As a result, the floor surface member is not easily damaged.

  In the test apparatus described above, the thickness of the floor surface member can be set to a predetermined value or less, and there can be no large step in the path from the fixed floor to the test execution unit through the floor surface member. Thereby, the operation | work which arrange | positions the member which fills a level | step difference becomes unnecessary. As a result, the test object can be more easily moved to the place where the test execution unit is arranged.

  The plurality of load receiving jigs may be movable in the horizontal direction in the entire region within the missing portion. As described above, since the horizontal movement of the plurality of load receiving jigs is not limited, the test execution unit can move smoothly when moving in the horizontal direction.

  The test apparatus may further include a movement limiting member that allows at least a part of the plurality of load receiving jigs to move in the horizontal direction in a partial region of the missing portion. Thereby, a plurality of load receiving jigs do not move to a biased position. As a result, the floor surface member is reliably supported by the load receiving jig.

  The plurality of load receiving jigs may be cylindrical, cylindrical, or spherical members. Thereby, it is hard to stop a load receiving jig in the predetermined position of a missing part.

  In the test apparatus according to the present invention, the test object can be easily moved.

1. First Embodiment (1) Overall Configuration of Test Apparatus The test apparatus of the present invention will be described below. First, the overall configuration of the test apparatus 100 according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a test apparatus according to the present embodiment. The test apparatus 100 according to the present embodiment is a test apparatus for performing a vibration test of a vehicle as the test object V.
In the present embodiment, the vehicle that is the test object V is a four-wheeled vehicle (for example, an automobile), but is not limited thereto, and is a vehicle having an arbitrary number of wheels such as a two-wheeled vehicle such as a motorcycle. Also good. In addition, buildings may be used as test objects. The number of moving vibration parts shown below can be changed according to the test object.

As shown in FIG. 1, the test apparatus 100 mainly includes a fixed floor 1, a first moving vibration unit 3a, and a second moving vibration unit 3b.
The fixed floor 1 is installed on the base surface G where the test apparatus 100 is installed. The base surface G is provided with a first missing portion H1 and a second missing portion H2 having a depth smaller than the first missing portion H1, and the fixed floor 1 is provided at the second missing portion H2. On the other hand, a vibration part 31 (described later) of a first moving vibration part 3a (described later) and a second moving vibration part 3b (described later) is installed in the first missing part H1.

The fixed floor 1 includes a lower fixed floor 11, a heat insulating member 13, and an upper fixed floor 15. The lower fixed floor 11 is a plate member made of metal such as stainless steel, and is installed on the main surface of the second missing portion H2 via an attachment member. Further, an opening is provided in a region corresponding to the first missing portion H1 of the lower fixed floor 11.
In addition, in order to ensure the heat insulation of the 3rd missing part H3 (FIG. 3), it is preferable that the lower fixed floor 11 shall have heat insulation.

The heat insulating member 13 is installed on the main surface of the lower fixed floor 11 on the side where the test object V is installed. The heat insulating member 13 is provided with an opening larger than the opening provided in the lower fixed floor 11 (that is, larger than the region corresponding to the first missing portion H1). Thereby, the moving panels 33 (described later) of the first moving vibration unit 3 a and the second moving vibration unit 3 b can move between the lower fixed floor 11 and the upper fixed floor 15. Hereinafter, a region formed by the opening provided in the heat insulating member 13 is referred to as a third missing portion H3 (FIG. 3). The heat insulating member 13 is a member made of a heat insulating material, and insulates the base surface G and the space S (described later).
In the case of the test apparatus 100 that does not require heat insulation, the heat insulation member 13 is not used, and another member such as a metal plate member may be used instead of the heat insulation member 13.

  The upper fixed floor 15 is a plate member made of metal such as stainless steel like the lower fixed floor 11, and is the main surface on the side where the test object V is installed (hereinafter, the main surface on the side where the test object V is installed). The surface is referred to as “floor level”) and is installed on the upper main surface of the heat insulating member 13 so that the height of the surface matches the height of the surface of the base surface G. Thereby, when installing the test object V in the test apparatus 100, the level | step difference between the base surface G and the test apparatus 100 can be eliminated. As a result, the test object V can be easily moved to the test apparatus 100. Similarly to the lower fixed floor 11, the upper fixed floor 15 is provided with an opening in a region corresponding to the first missing portion H1. Hereinafter, a region formed by the opening provided in the upper fixed floor 15 is referred to as a fourth missing portion H4 (FIG. 3).

The opening provided in the lower fixed floor 11 and the opening provided in the upper fixed floor 15 may have different sizes. Moreover, in order to ensure the heat insulation of the 3rd missing part H3 (FIG. 3), it is preferable that the upper fixed floor 15 shall have heat insulation.
Since the fixed floor 1 has the third missing portion H3, at least one of the lower fixed floor 11 and the upper fixed floor 15 has heat insulating properties from the viewpoint of ensuring the heat insulating property of the third missing portion H3. It is preferable that However, when heat insulation is not required, a heat insulating material may not be used.

  Moreover, the shape of the opening provided in the lower fixed floor 11, the heat insulating member 13, and the upper fixed floor 15 is an arbitrary shape according to the moving range of the vibration part 31 (described later) such as a circle, an ellipse, and a rectangle. Can do. However, at least the shape of the opening (fourth missing portion H4) provided in the upper fixed floor 15 is curved when the shape of the opening has a corner such as a rectangle. It is preferable. Thereby, it can suppress that the load receiving jig 37 (FIG. 3) arrange | positioned at the 4th missing part H4 stops at the corner | angular of an opening during a movement. That is, the load receiving jig 37 can be moved smoothly.

  As shown in FIG. 2, the first moving vibration unit 3 a is installed in the first missing portion H <b> 1 on the back side when viewed from the entrance door E. FIG. 2 is a view of the test apparatus as viewed from above (toward the ceiling). When the test is executed, the front wheels of the four test objects V are placed on the first moving vibration unit 3a. In addition, the first moving vibration unit 3a is movable in the vertical direction on the paper surface in synchronization with the first moving vibration unit 3a on the upper side of the paper in FIG. 2 and the first moving vibration unit 3a on the lower side. .

  When the first moving vibration unit 3a moves in the vertical direction on the paper surface, for example, when the first moving vibration unit 3a on the upper surface of the paper moves downward, the first moving vibration unit 3a on the lower surface of the paper moves upward. Each moves the same distance in the opposite direction. Thereby, the 1st movement vibration part 3a can be appropriately moved according to the place between the front wheels of the test object V or the place where the front wheels are installed.

  As described above, the first moving vibration unit 3a of the present embodiment is movable only in the vertical direction of the paper, but is not limited thereto. It may have the same configuration as a second moving vibration unit 3b described later, and may be movable in the vertical and horizontal directions on the paper surface, or may be movable only in the horizontal direction on the paper surface. Further, the first movement vibration unit 3a on the upper side of the paper and the first movement vibration unit 3a on the lower side of the paper may be movable without being synchronized.

  Moreover, the load receiving jig 37 (FIG. 3), which will be described later, is not disposed in the fourth missing portion H4 (FIG. 3) in the first moving vibration part 3a of the present embodiment. This is because the test object V hardly passes over the floor surface member 35 (FIG. 3) of the first moving vibration unit 3a. However, the present invention is not limited to this, and the load receiving jig 37 may be installed also in the fourth missing portion H4 of the first moving vibration portion 3a. Thereby, even when the position of the test object V is shifted when the test object V is arranged in the test apparatus 100, the floor surface member 35 can be prevented from being bent due to the weight of the test object V.

  The second moving vibration part 3b is arranged at a position corresponding to the first missing part H1 closer to the entrance door E than the first moving vibration part 3a. When the test is performed, the rear wheels of the four test objects V are placed on the second moving vibration unit 3b. In addition, the second moving vibration unit 3b is movable in the vertical and horizontal directions on the paper surface in synchronization with the second moving vibration unit 3b on the upper side and the lower second moving vibration unit 3b in FIG. Yes.

  When the two second moving vibration units 3b move in the vertical direction on the paper surface, each moves in the vertical direction on the paper surface in the opposite direction by the same distance as the first moving vibration unit 3a. Further, the second moving vibration unit 3b moves together with the first moving vibration unit 3a without changing the positional relationship in the horizontal direction of the paper surface with the first moving vibration unit 3a when moving in the vertical direction on the paper surface. It may be possible, or may be movable independently of the first moving vibration part 3a. Thereby, the 2nd movement vibration part 3b can be appropriately moved according to the width | variety between the rear wheels of the test object V like the 1st movement vibration part 3a.

  As described above, the second moving vibration unit 3b of the present embodiment is movable in the vertical and horizontal directions on the paper surface, but is not limited thereto. It may have the same configuration as the first moving vibration unit 3a described above, and may be movable only in the vertical direction of the paper surface, or may be movable only in the horizontal direction of the paper surface. Further, the second moving vibration part 3b on the upper side of the paper and the second movement vibration part 3b on the lower side of the paper may be movable without being synchronized.

Further, when moving in the left-right direction on the paper surface, the second moving vibration unit 3b changes the positional relationship in the left-right direction between the upper second moving vibration unit 3b and the lower second moving vibration unit 3b. Move without. Thereby, the distance between the front wheel and the rear wheel of the test object V is determined without shifting the positional relationship between the upper second moving vibration part 3b and the lower second moving vibration part 3b. It can move to correspond to (wheelbase).
In addition, it may be movable while the positional relationship between the second movement vibration unit 3b on the upper side of the paper and the second movement vibration unit 3b on the lower side of the paper is changed.

  The details of the configuration of the first moving vibration unit 3a and the second moving vibration unit 3b will be described later.

  The test apparatus 100 further includes a space blocking unit 5. The space blocking unit 5 is a wall that blocks the external space and the space S in which the test object V is disposed during the vibration test. Accordingly, the space blocking unit 5 is a hollow box-shaped member formed of a metal plate such as stainless steel having a structure in which a heat insulating material is sandwiched, for example. The hollow portion of the space blocking part 5 corresponds to the space S. Since the test apparatus 100 includes the space blocking unit 5, an environment having various conditions (temperature, humidity, etc.) can be created inside the space S. As a result, the vibration test of the test object V in various environments can be executed.

In addition, the space blocking unit 5 is provided with an opening having a size capable of passing the test object V. An entrance door E is provided at the opening of the space blocking unit 5. When moving the test object V into the space S, the entrance door E is opened, and the test object V is moved into the space S from the opening of the space blocking unit 5. On the other hand, during the vibration test, the entrance door E is closed, and the space S and the external space are isolated.
If it is not necessary to control the test environment of the test object V, the space blocking unit 5 may be omitted from the test apparatus 100.

(2) Configuration of Movement Vibration Unit Next, the configuration of the first movement vibration unit 3a and the second movement vibration unit 3b will be described with reference to FIG. FIG. 3 is a diagram illustrating a detailed configuration of the moving vibration unit. In the following description, the configuration of the second moving vibration unit 3b will be described as an example. This is because, as described above, the first moving vibration portion 3a and the second moving vibration portion 3b are such that the first moving vibration portion 3a can move only in the vertical direction of the paper (therefore, the load receiving jig 37 is omitted). This is because it has the same configuration except that it is possible.
The second moving vibration unit 3 b includes a vibration unit 31, a moving panel 33, a floor surface member 35, and a plurality of load receiving jigs 37.

  As described above, the vibration unit 31 (an example of the test execution unit) is installed in the first missing portion H1. The vibration unit 31 vibrates mainly in the vertical direction (vertical vertical direction) based on an instruction from a control unit (not shown) or the like. The vibration unit 31 may be capable of vibrating not only in the vertical vertical direction but also in the horizontal direction and vertical direction (horizontal direction perpendicular to the vertical direction) of the drawing. Further, in the vibration part 31, the two first movement vibration parts 3a and the two second movement vibration parts 3b may vibrate in synchronization with each other, or may vibrate independently. Thereby, the vibration part 31 can give various vibrations to the test object V for a vibration test.

  The movable panel 33 is movably installed in a third missing portion H3 between the lower fixed floor 11 and the upper fixed floor 15 of the fixed floor 1. That is, the movable panel 33 is movably installed below the upper fixed floor 15 of the fixed floor 1. Further, the movable panel 33 is fixed at a predetermined position of the vibration unit 31. As a result, the moving panel 33 is moved to the first position as the vibration unit 31 moves within the region defined by the first missing portion H1 (or the fourth missing portion H4 (described later)) based on a command from the control unit or the like. 3 It is possible to move in the horizontal direction within the missing part H3.

  Moreover, in order to ensure the heat insulation of space S and the 1st missing part H1, it is preferable that the movable panel 33 shall have heat insulation, but when it is the test apparatus 100 which does not require heat insulation, heat insulation is demonstrated. It is not necessary to have.

  As described above, in order to allow the vibration unit 31 to move within the region defined by the first missing portion H1 (fourth missing portion H4), the fixed floor 1 and the moving panel 33 of the third missing portion H3. It is preferable that the area (in the horizontal direction) of the region surrounded by is greater than or equal to the area (in the horizontal direction) of the region where the vibration unit 31 can move. For example, the area (in the horizontal direction) of the region surrounded by the fixed floor 1 and the moving panel 33 of the third missing portion H3 is set to be equal to or greater than the horizontal area of the first missing portion H1 (fourth missing portion H4). Thereby, the vibration part 31 can be moved over the whole area | region of the 1st missing part H1 (4th missing part H4).

  The floor surface member 35 is a plate-like member having a thickness equal to or less than a predetermined value made of metal such as stainless steel. Further, the floor surface member 35 has a sufficient area that can cover the fourth missing portion H4 when disposed on the upper fixed floor 15. Further, the floor surface member 35 is fixed to a predetermined position of the movable panel 33 or the vibration unit 31. As a result, the floor surface member 35 moves in the horizontal direction in accordance with the movement of the moving panel 33 (or the vibration unit 31) while covering the fourth missing portion H4.

  The thickness of the floor surface member 35 determines the height of the step between the floor surface member 35 and the upper fixed floor 15. In the present embodiment, the thickness of the floor surface member 35 (that is, the step between the floor surface member 35 and the upper fixed floor 15) is preferably, for example, 10 mm or less, and is 5 mm or less, which is a barrier-free step reference. More preferably it is. Thereby, the test object V can be easily moved into the test apparatus 100 without installing a slope or the like.

  The plurality of load receiving jigs 37 are cylindrical metal members having sufficient strength at least in the length (height) direction. The load receiving jig 37 is arranged in a state where one end in the length direction is in contact with the main surface of the movable panel 33 in the fourth missing portion H4. Moreover, the height of the cylindrical load receiving jig 37 is substantially the same as the height of the fourth missing portion H4 (that is, the thickness of the upper fixed floor 15). Thereby, the other end in the length direction of the load receiving jig 37 can come into contact with the floor surface member 35 when the test object V is on the floor surface member 35.

  That is, when the test object V is on the floor surface member 35, one end of the load receiving jig 37 contacts the moving panel 33 and the other end contacts the floor surface member 35. As a result, the load receiving jig 37 can receive the load of the test object V from the floor surface member 35 together with the movable panel 33. Thereby, even when the thickness of the floor surface member 35 is thin and its rigidity is low, the floor surface member 35 does not bend greatly when the test object V passes over the floor surface member 35. As a result, the floor surface member 35 is not easily damaged.

  As described above, when the test object V is on the floor surface member 35, if the floor surface member 35, the movable panel 33, and the load receiving jig 37 can come into contact with each other, the above effect can be exhibited. The height of the receiving jig 37 may not coincide with the height of the fourth missing portion H4 (the thickness of the upper fixed floor 15). For example, the height of the load receiving jig 37 is preferably slightly lower than the height of the fourth missing portion H4.

  By making the height of the load receiving jig 37 slightly lower than the height of the fourth missing portion H4, it becomes difficult for the floor surface member 35 and the load receiving jig 37 to come into contact during the movement of the floor surface member 35. That is, during the movement of the floor surface member 35, it becomes difficult for friction to occur between the floor surface member 35 and the load receiving jig 37. As a result, it becomes difficult to generate a large noise or to prevent the movement of the floor surface member 35 and / or the load receiving jig 37.

In addition, since the load receiving jig 37 has a cylindrical shape, the load receiving jig 37 stays at a corner of the fourth missing portion H4 or abuts with another load receiving jig 37, so that a predetermined amount is obtained. Will not stop in position. If the shape of the load receiving jig 37 has a curved shape such as a columnar shape or a spherical shape in addition to the cylindrical shape, the above effect can be exhibited.
Although the possibility of staying occurs, the load receiving jig 37 may have a shape such as a square cylinder or a prism. In this case, it is preferable that the shape of the load receiving jig 37 is a square shape close to a cylinder.

  Furthermore, it is preferable that the number of load receiving jigs 37 is typically about 60% to 90% of the maximum number (maximum filling number) in which the load receiving jigs 37 can be filled in the fourth missing portion H4. More preferably, it is about 90%. Thereby, when the vibration part 31 moves, the load receiving jig 37 can move smoothly without falling down in a form pushed away by the vibration part 31 and a form filling the path after the vibration part 31 passes.

  Moreover, since the number of load receiving jigs 37 is an appropriate number without being too small, for example, the position of the load receiving jig 37 is biased when the test object V passes through the floor surface member 35. There is no. That is, the test object V cannot be supported at a certain location.

(3) Operation of Test Device Next, an operation when performing a vibration test of the test object V using the test device 100 will be described. First, before performing the vibration test, the first moving vibration unit 3a is covered with the fourth missing portion H4 by the floor surface member 35 according to the dimension of the test object V (for example, the distance between the wheels). And the 2nd movement vibration part 3b is moved by moving the vibration part 31. FIG. As the vibration unit 31 moves, the moving panel 33 moves in the horizontal direction below the upper fixed floor 15. In the above case, the fourth missing portion H4 is covered with the floor surface member 35 before and after the movement of the first moving vibration portion 3a and the second moving vibration portion 3b.

  At this time, since the load receiving jig 37 has a cylindrical shape, it is difficult to stop at a predetermined position of the fourth missing portion H4. Further, the load receiving jig 37 is movable in the horizontal direction in the entire region within the fourth missing portion H4. As a result, the load receiving jig 37 can freely move within the fourth missing portion H4 without being hindered by horizontal movement. As a result, the first moving vibration unit 3a and the second moving vibration unit 3b can move smoothly.

  Note that the movement positions of the first movement vibration unit 3a and the second movement vibration unit 3b may be set and adjusted by an operator using a control unit or the like. Alternatively, the position corresponding to each test object V is stored in the control unit or the like, the operator designates the test object V to be subjected to the vibration test in the control unit, and the control unit automatically performs the first operation. The movement vibration unit 3a and the second movement vibration unit 3b may be moved to positions corresponding to the test objects V.

  After the first moving vibration unit 3a and the second moving vibration unit 3b are moved to predetermined positions, the front wheel of the test object V is placed on the vibrating unit 31 of the first moving vibration unit 3a, and the rear wheel is moved to the second moving vibration unit 3b. Therefore, the test object V is moved from the base surface G through the fixed floor 1 (upper fixed floor 15) and the floor surface member 35 into the test apparatus 100.

  At this time, as described above, there is a large step in the path along which the test object V moves from the base surface G through the fixed floor 1 (upper fixed floor 15) and the floor surface member 35 to the vibrating portion 31. Does not exist. This eliminates the need for work such as arranging a member that fills the steps.

  Further, while the test object V is passing through the floor surface member 35 (that is, when the test object V exists on the floor surface member 35), both ends in the length direction of the load receiving jig 37 are respectively movable panels. 33 and the floor surface member 35. Thereby, the load receiving jig 37 can support the test object V together with the movable panel 33. As a result, the floor surface member 35 is difficult to bend.

  After the test object V is arranged on the vibration part 31, each wheel of the test object V is fixed to the vibration part 31 using a jig (not shown) or the like as necessary. Thereafter, all the workers are retreated from the space S, the entrance door E is closed, and if necessary, the air conditioner provided at a predetermined position of the space blocking unit 5 is used to enter the space S. Produces an environment of atmospheric conditions.

  After creating a predetermined environment in the space S as necessary, the vibration unit 31 vibrates with respect to the test object V in a state where the test object V is lifted to a predetermined height (for example, about 10 cm). And the vibration test of the test object V is performed.

  In addition, in operation | movement of said test apparatus 100, in the range which does not exceed the range of this invention, each operation | movement can be changed arbitrarily and the order of each operation | movement can be changed.

(4) Effects of Embodiment The effects of the first embodiment can be described as follows.
The test apparatus (for example, the test apparatus 100) of the first embodiment is a test apparatus that performs a test by vibrating or running a test object (for example, the test object V), and is a fixed bed (for example, an upper fixed bed). 15), a test execution unit (for example, vibration unit 31), a moving panel (for example, moving panel 33), a floor surface member (for example, floor surface member 35), and a plurality of load receiving jigs (for example, load) Receiving jig 37). The fixed floor is provided with a missing part (for example, a fourth missing part H4). The test execution unit is arranged corresponding to the missing part and executes a test (for example, vibration test) of the test object. The moving panel is installed below the fixed floor and can move in the horizontal direction as the test execution unit moves. The floor surface member is arranged on the fixed floor so as to cover the missing portion, and moves in the horizontal direction in accordance with the movement of the moving panel in a state where the missing portion of the fixed floor is covered. The plurality of load receiving jigs are disposed on the movable panel in the missing portion. Further, the load receiving jig receives the load from the floor surface member together with the movable panel at least when the test object is on the floor surface member.

In the test apparatus of the first embodiment, first, the test execution unit is moved to a predetermined position corresponding to the test object. As the test execution unit moves, the moving panel moves in the horizontal direction. Then, the test object is moved to the arrangement position of the test execution unit through the floor table surface material from the fixed bed. Thereafter, the test is started by the test execution unit.

  In the test apparatus of the first embodiment, a load receiving jig is arranged in a missing portion of the fixed floor, and the load receiving jig moves the load from the floor surface member when the test object is on the floor surface member. Receive with the panel. As a result, when the test object passes over the floor surface member, the floor surface member does not bend greatly even if the thickness of the floor surface member is as thin as a predetermined value or less and its rigidity is low. As a result, the floor surface member is not easily damaged.

  In the test apparatus of the first embodiment, the thickness of the floor surface member can be set to a predetermined value or less, and there is no large step in the path from the fixed floor to the test execution unit through the floor surface member. Thereby, the operation | work which arrange | positions the member which fills a level | step difference becomes unnecessary. As a result, the test object can be more easily moved to the place where the test execution unit is arranged.

  The plurality of load receiving jigs can move in the horizontal direction in the entire region within the missing portion. As described above, since the horizontal movement of the plurality of load receiving jigs is not limited, the test execution unit can move smoothly when moving in the horizontal direction.

  The plurality of load receiving jigs are cylindrical, cylindrical, or spherical members. Thereby, it is hard to stop a load receiving jig in the predetermined position of a missing part.

(5) Other Embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. In particular, a plurality of embodiments and modifications described in this specification can be arbitrarily combined as necessary.
(A) Other Embodiment Regarding Arrangement of Load Receiving Jig In the first embodiment described above, a plurality of load receiving jigs 37 are arranged so as to be movable in the horizontal direction over the entire region of the fourth missing portion H4. It was. However, the load receiving jig 37 is only required to be disposed at a necessary place and receive the load from the floor surface member 35 together with the movable panel 33. Therefore, the arrangement method in the missing portion is not particularly limited.
For example, the test apparatus may further include a movement limiting member that allows the plurality of load receiving jigs to move in the horizontal direction in a partial region of the missing portion.

  For example, as shown in FIG. 4A, each of the load receiving jigs 37 is fixed to one end of an elastic member 41 (an example of a movement limiting member) such as a spring, and the other end of the elastic member 41 is connected to the vibrating portion 31 and the fourth. By fixing to the side wall (thickness portion of the upper fixed floor 15) of the missing portion H4, the movement of the load receiving jig 37 can be limited within a predetermined range. At this time, as shown in FIG. 4A, one load receiving jig 37 is connected to the side wall of the vibration part 31 and the fourth missing part H4 via a plurality of load receiving jigs 37 connected by the elastic member 41. May be. FIG. 4A is a diagram illustrating an example of another embodiment of the arrangement of the load receiving jig.

  Alternatively, as shown in FIG. 4B, a plurality of separation curtains 43 (movement restricting members) formed of an elastic material such as rubber, one end connected to the vibrating portion 31 and the other end connected to the side wall of the fourth missing portion H4. For example, the fourth missing portion H4 may be divided into a plurality of regions, and the load receiving jig 37 may be disposed in each of the divided regions. FIG. 4B is a diagram illustrating a further example of another embodiment of the arrangement of the load receiving jig.

  As described above, by restricting the movement of the load receiving jig 37 within a predetermined range, it is difficult for the load receiving jig 37 to move to a biased position. As a result, a portion that is not supported by the load receiving jig 37 in the floor surface member 35 hardly occurs (that is, the floor surface member 35 can be reliably supported by the load receiving jig 37).

  Further, as described above, by restricting the movement of the load receiving jig 37 within a predetermined range, the load receiving jig 37 is compared with the case where the load receiving jig 37 is arranged without restricting the movement. Even if the number of 37 is reduced (for example, reduced to about 40% of the maximum filling number), the location where the load receiving jig 37 exists is biased and the portion where the test object cannot be supported can be eliminated.

(B) Other Embodiments of Floor Surface Member In the first embodiment, the floor surface member 35 is a plate-like member. However, the present invention is not limited to this. For example, a gentle slope is formed at the end of the floor surface member 35 (at least the end on the path through which the test object V passes) by cutting the end of the floor surface member 35. May be provided. Thereby, for example, even if the thickness of the floor surface member 35 is increased in order to improve the strength, the floor level of the fixed floor 1 (upper fixed floor 15) and the floor level of the floor surface member 35 can be reduced to a predetermined height or less. (That is, it can be avoided that a large step is formed between the floor level of the fixed floor 1 (upper fixed floor 15) and the floor level of the floor surface member 35).

(C) Other Embodiments of Test Execution Unit In the test apparatus 100 of the first embodiment described above, the vibration unit 31 is used as the test execution unit. However, the present invention is not limited to this, and as a test execution unit, travel for measuring various characteristics related to travel of the vehicle as the test object V, for example, rotation characteristics of the wheels (that is, travel characteristics of the test object V). May be used.

  For example, when the wheel disposed on the cylindrical member that can rotate around the central axis is rotated, the rotational speed or rotational torque of the cylindrical member is used as the traveling unit for measuring the rotational characteristics of the wheel. There is a traveling part that can be measured as a chassis dynamo. In such a traveling unit, for example, the rotation speed of the wheel and the torque generated by the rotation of the wheel (for example, the rotation-torque characteristics of the wheel) are measured from the measured rotation speed and rotation torque of the cylindrical member. it can.

  The present invention can be widely applied to a test apparatus for performing various tests on a test object.
