Description
Technical field
The utility model relates to the device measuring rotating shaft moment size in aircraft wind-tunnel experimentation, especially a kind of rotating shaft torque measuring device.
Background technology
The catanator of aircraft is generally the deflection being controlled control surface by mechanical transfer, in order to the position making control surface deflect into needs, must overcome the rotating shaft moment acted on rudderpost.In airplane design process, need to carry out wind tunnel test to the control surface of flaperon, elevating rudder, flying tail, yaw rudder, front wing and so on, to measure the rotating shaft moment of control surface.The basic demand of aircraft to control surface is: control surface can produce enough operating torques, to ensure that aircraft can fly under required state, the time that control surface deflects into required angle is short, to ensure that aircraft has good maneuverability, meet the size that these requirements must know the rotating shaft moment of control surface, to design the booster of suitable control surface.Namely the object of wind-tunnel rotating shaft torque test is to measure and acts on the moment of the aerodynamic force on aircraft control surface to its rotating shaft.The rotating shaft torque measuring device of existing slice structure is subject to the restriction of wing space size, and cause the structure designed cannot play best usefulness, measuring error is larger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of rotating shaft torque measuring device, to reduce or to avoid problem noted earlier.
Specifically, the utility model provides a kind of rotating shaft torque measuring device, for measuring the rotating shaft moment of the rotating shaft supporting control surface in wind tunnel experiment, described rotating shaft torque measuring device comprises one and holds the rotating shaft fixed part of described rotating shaft, an installation portion and a Response Division be connected with described rotating shaft fixed part and described installation portion respectively tightly, and described rotating shaft fixed part has an axle sleeve that can pass for described rotating shaft; Described Response Division has two outstanding kinks downwards in the side of adjacent described installation portion; The first breach that the width that each described kink all has an opening upwards is equal.
Preferably, the side that described installation portion adjoins described kink has second breach that Open Side Down, and the width of described first breach equals 2/3 of the width of described second breach; Have the 3rd breach that Open Side Down between described two kinks, the width of described 3rd breach equals the width of described second breach.
Rotating shaft torque measuring device of the present utility model by the rotating shaft of installation portion cantilever support, rotating shaft fixed part and Response Division not with other form touch, measurement data by the impact of other structure, does not improve measuring accuracy.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein,
Fig. 1 display be the structural representation of rotating shaft torque measuring device according to a specific embodiment of the present utility model.
Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.Wherein, identical parts adopt identical label.
Fig. 1 display be the structural representation of rotating shaft torque measuring device according to a specific embodiment of the present utility model.As shown in the figure, rotating shaft torque measuring device of the present utility model is used for the rotating shaft moment measuring the rotating shaft 11 supporting control surface in wind tunnel experiment, and wherein, described control surface can be the flaperon, elevating rudder, yaw rudder, front wing etc. of model aircraft.
Specifically, rotating shaft torque measuring device of the present utility model comprises installation portion 42 and the Response Division 43 be connected with rotating shaft fixed part 41 and installation portion 42 respectively of rotating shaft 11 described in rotating shaft fixed part 41, cantilever support of holding the rotating shaft 11 supporting control surface tightly, and the measurement mechanisms such as foil gauge can be pasted in the surface of Response Division 43.Rotating shaft fixed part 41 has an axle sleeve 411 that can pass for rotating shaft 11; The two ends of axle sleeve 411 have the spaced auricle 412 of two couple be fixedly connected with it respectively; Two pairs of auricles 412 has respectively the screw hole 413 that the screw (not shown) for adjusting spacing between two pairs of auricles is passed.Response Division 43 is arranged on described two middles to spaced auricle, and described Response Division 43 links into an integrated entity with described axle sleeve 41.
In a specific embodiment, Response Division 43 has two kinks 431 given prominence to downwards in the side of adjacent installation portion 42; The first breach 432 that the width that each kink 431 all has an opening upwards is equal.The side that installation portion 42 adjoins described kink 43 has second breach 421 that Open Side Down, and the width of described first breach 432 equals 2/3 of the width of described second breach 421.Have the 3rd breach 422 that Open Side Down between described two kinks 431, the width of described 3rd breach 422 equals the width of described second breach 421.
Because rotating shaft torque measuring device of the present utility model is by installation portion 42 cantilever support rotating shaft 11, rotating shaft fixed part 41 and Response Division 43 not with other form touch, therefore measurement data can not be subject to the impact of other structure, improves measuring accuracy.In addition, in the structure of rotating shaft torque measuring device of the present utility model, Response Division 43 have employed the design of flexible beam, that is, be provided with kink 431, multiple breach 432,421,422 in Response Division 43, the setting of these structures, add the length of Response Division 43 on the one hand, also reduce the rigidity of Response Division 43 on the other hand, thus add the flexibility of Response Division 43, make the foil gauge 44 on Response Division 43 can obtain deflection large as far as possible.
In addition; the selection of the numerical range of the width of the first breach 432 and the second breach 421, the 3rd breach 422; be based on improving chancing on of measuring accuracy in experimentation; when there is no coherent reference data; find according to groping; set one group of such numerical range; measuring accuracy can be improved about 10%; this is quite unexpected in this area; although its principle is difficult to explain; but effect is non-obvious really, therefore the utility model is recorded in this and is protected.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle, amendment and combination, all should belong to the scope of the utility model protection.
