Embodiments of a bar arrangement design support apparatus and bar arrangement design support program according to the present invention will be described below in detail with reference to the drawings.
FIG. 11 is a block diagram showing an outline of a bar arrangement design support apparatus according to an embodiment of the present invention.

  This arrangement design support device is designed to generate design housing data including an input means for performing an input operation following design data, and a cross-sectional list of the housing and axis position data based on input information obtained from the input means. Based on the frame data generation means, the design frame database for storing the design frame data, and the design frame data and the reinforcing bar calculation rules, such as the attributes of the reinforcing bars, the covering of the reinforcing bars, the fixing length, the hook claw length, the bending R part, etc. Reinforcing bar calculation means for generating reinforcing bar data, a reinforcing bar calculation rule database for storing the reinforcing bar calculation rule for deriving the reinforcing bar data from the design frame data, and a frame for creating three-dimensional frame skin data from the design frame data Skin calculation means, reinforcing bar calculation means for creating three-dimensional reinforcing bar data from the reinforcing bar data, frame skin calculation means and reinforcing bar calculation Graphic data for storing graphic data (designed body data, body skin data, reinforcing bar data, etc.) derived in steps in a predetermined file format, data retrieval means for retrieving information designated from each database, and the data retrieval Image editing means for generating and outputting the graphic data retrieved by the means as an image.

  This bar arrangement design support apparatus functions as the bar arrangement design support apparatus by installing a bar arrangement design support program in a computer system, and the various functional means and databases are arranged and linked to a plurality of computers on a network. It can also be deployed as a distributed object type that operates in

  The individual reinforcing bar data generated by the reinforcing bar calculation means includes a unique index ID, name, material, radius, position coordinates of a line segment representing a shape, and a triangle group representing a skin (FIG. 14B). Are stored in the graphic database.

A line segment expressing the shape of the reinforcing bar is composed of a straight portion, a curved portion, and a bent R portion (FIG. 14A).
The curved portion excluding the curved portion made up of arcs is processed by being divided into a plurality of temporarily subdivided arcs within the range allowed for calculation accuracy, for the convenience of display of the bar arrangement design support apparatus.
Further, when the curved portion is deformed or when the moving surface S1 or the deformed surface S2 is formed, the curve is temporarily divided into a plurality of straight lines and processed.

The bent portion R is formed at a bent portion of a reinforcing bar. (Figure 14 (C))
The bending R portion is an arc applied when bending a reinforcing bar, and its specification is defined in consideration of the diameter and material of the reinforcing bar.
Rule information for deriving a specific specification of the bending R portion from the diameter and material of the reinforcing bar is input in advance into the reinforcing bar calculation rule database, and is searched by the data search means using the reinforcing bar diameter and material as a key. The

In this example, as a function of editing or correcting the reinforcing bar data, as a result of moving the specified reinforcing bar A, interference with other reinforcing bars or poor linkage with other reinforcing bars occurs. Interference avoiding means for correcting the position data so as to avoid the interference or the linkage failure is provided (see FIGS. 3 and 11).
At that time, the reinforcing bar design support device includes designated reinforcing bar position detecting means 3 as a function of detecting position data of the designated reinforcing bar A before and after the movement of the designated reinforcing bar A (see FIG. 12).

  For example, the specified reinforcing bar position detection means 3 displays a straight line perpendicular to the screen passing through the screen coordinates (position coordinates in the screen coordinate system) of the cursor operated by the input means such as a mouse on the screen displaying the bar arrangement state. The straight line is converted into real coordinates using a transformation matrix, the graphic data DB is searched, and a reinforcing bar that intersects with the straight line or a reinforcing bar within a specified distance from the straight line is detected from the graphic data DB. As the specified reinforcing bar A, a process of deriving and storing the position data of the vertices constituting the core wire a of the specified reinforcing bar A is performed.

The reinforcing bar design support device of this example includes reinforcing bar discrimination means for discriminating the attributes of the specified reinforcing bar A detected by the specified reinforcing bar position detection means 3 based on processing to be performed.
The attributes mentioned here are “rebar part”, “rebar diameter”, “rebar name”, etc., and “rebar part”, “rebar diameter”, “rebar name” are input when inputting a cross section of a list of beams, etc. Information is given as attribute data to each reinforcing bar created from the cross-section list and the axis alignment of the frame.
In addition, the attribute data includes a “deformation” switch as a switch for selecting either the specified reinforcing bar A or the secondary reinforcing bar B as a reinforcing bar to be deformed.
In this example, when the “deformation” switch = on, the specified reinforcing bar A itself is selected as an object of deformation.

In this example, the attribute data is added to the reinforcing bar data when the reinforcing bar data is generated.
The attribute data includes, for example, “rebar part” = beam, “rebar diameter” = D13, “rebar name” = stirrup, or “rebar” with “rebar part”, “rebar diameter” and “rebar name” as indexes. “Part” = beam, “rebar diameter” = all, “rebar name” = stirrup, etc., and the “deformation” switch searches for the specified rebar A on condition, and selects the specified rebar A, By operating the cursor on the screen with a mouse or the like, the “deformation” switch = ON / OFF is recorded.

Hereinafter, a means for avoiding interference and the like when the “deformation” switch is OFF will be described.
In this example, as a function of editing or correcting the reinforcing bar data, position data of a single or a plurality of secondary reinforcing bars B in which interference occurs as a result of moving the specified reinforcing bar A while avoiding the interference are described. Interference or the like avoiding means for performing correction to retract the interference part B in the moving direction of the designated reinforcing bar A (see FIG. 3).

[Interference avoidance measures]
In this example, the means for avoiding interference, etc. specifies a slave bar B that causes interference with the designated reinforcing bar A based on the ID of the designated reinforcing bar A along with the movement of the designated reinforcing bar A, and position data of the slave bar B Is immediately changed to position data that can avoid interference, and related graphic data that changes accordingly is changed (see FIG. 13).
The avoidance means such as interference in this example includes an interference detection means 1 for detecting presence / absence of interference with the secondary reinforcing bar B accompanying the movement of the specified reinforcing bar A, and movement of the specified reinforcing bar A through the interference portion of the secondary reinforcing bar B. An interference correction unit 2 is provided that moves the interference part in the direction by an amount that causes the interference part to disappear, or causes the interference part of the secondary reinforcing bar B to protrude into a shape that causes the interference part to disappear in the movement direction of the designated reinforcing bar A (see FIG. 12).

<Interference detection means>
The interference detection means 1 includes a movement trajectory detection means 4 that guides the entire movement trajectory formed as the designated reinforcing bar A is moved as one surface (hereinafter referred to as “movement surface S1”), and the designation. The crossover detection means 5 that specifies the secondary reinforcing bar B that intersects the moving surface S1 accompanying the movement of the reinforcing bar A and guides the crossing portion of the secondary reinforcing bar B is combined.

The interference detection means 1 detects the position data of the start and end of the specified reinforcing bar A detected by the specified reinforcing bar position detecting means 3, and the position of the movement position of the specified reinforcing bar A according to the change of the screen coordinates of the cursor. Data is calculated and stored (see FIGS. 1 and 2).
The movement trajectory detecting means 4 defines a surface formed by the trajectory of the core wire a of the designated reinforcing bar A from the original position of the core wire a of the designated reinforcing bar A to the moving position as the moving surface S1, and the moving surface S1 is singular. Alternatively, a process is performed in which the position data is stored as two triangular vertices divided by a plurality of quadrilaterals and the vertices of each quadrilateral being divided by diagonal lines of the quadrilateral (see FIG. 1B).

Hereinafter, the operation of the movement trajectory detection means 4 when creating the moving surface S1 will be described for the case where the designated rebar A is a straight line or a curve and the case where the movement trajectory is a straight line or a curve, respectively.
(1) When the moving locus is a plane a) When the specified reinforcing bar A is a straight line The moving surface S1 is a single quadrilateral.
b) When the specified reinforcing bar A is a curve The core wire a is subdivided into straight lines that satisfy the desired accuracy, and a plurality of quadrilaterals connecting the nodes before and after the movement are formed.
(2) When the movement trajectory is a curved surface When the specified reinforcing bar A is a curved line, for example, a straight line (hereinafter referred to as a “starting end curve”) and an end (hereinafter referred to as a “ending curve”) that are the starting ends of the trajectory along which the specified reinforcing bar A moves. Are divided into the same number of straight lines satisfying the desired accuracy, and are defined as continuous line segments (hereinafter referred to as “start end continuous line segment” and “end continuous line segment”).
In this example, at that time, the core wire a of the designated reinforcing bar A is subdivided with a straight line that satisfies the desired accuracy, and the end points of the designated reinforcing bar A coincide with each other as the nodes of the starting end continuous line segment and the ending continuous line segment. The distance between each node is enlarged or reduced to copy.

Create a grid where the quadrilaterals are connected by connecting the corresponding nodes of the starting and ending continuous segments obtained as described above, and save the triangle coordinates that are divided by the diagonal line Perform (see FIG. 1B or FIG. 2A).
The grid is created by combining the node creation methods (1) and (2) above even if the specified reinforcing bar A and the movement trajectory are a mixture of a straight part, a curved part or a bent R part.

The intersection detection means 5 searches the graphic DB for the secondary reinforcing bar B that intersects the moving surface S1 by the data search means.
The intersection detection means 5 derives the intersection between the reinforcing bar data and the moving surface S1 for each secondary reinforcing bar B included in the searched secondary reinforcing bar group, and stores it as a secondary dividing point x (see FIG. 4). .

<Correction correction means>
In this example, the interference correction means 2 includes a deformation surface detection means 6 that guides a deformation surface S2 in which the secondary split point x of the secondary reinforcing bar B moves as the designated reinforcing bar A moves, and a movement position of the secondary reinforcing bar B. The movement point calculation means 7 for deriving the position of the subdivision point x, the deformation base point calculation means 8 for deriving the deformation base point p of the subrebar B, and the interference with the specified rebar A as the specified rebar A moves. The reinforcing bar deforming means 9 for deforming the secondary reinforcing bar B so as to avoid this and the data updating means 10 for updating the position data of the secondary reinforcing bar B immediately before retraction with the position data after retreating are combined (FIG. 12). reference).

The deformation surface detection means 6 determines the normal line of the deformation surface S2 as follows according to the line segment of the secondary reinforcing bar B including the secondary division point x.
(1) When the subdivision point x is on a curved part a) In principle, it is an arc included in the group of subdivided arcs constituting the curved part, and the normal line of the arc including the subdivision point x (FIG. 5A (See (B)).
b) When the subdivision point x is a connection point (node) with an adjacent arc, the average direction normal of both adjacent arc normals is used (see FIGS. 5A and 5B).
(2) When the subdivision point x is on a straight line portion a) When only the straight line portion is found The foot at the point where the foot is lowered from the subdivision point x to the specified reinforcing bar A of the moving position is obtained. The outer product direction of the direction of the foot and the direction of the specified reinforcing bar A is a normal line (see FIG. 4A).
b) When one end is connected to the curved portion as a tangent line The arc surface is normal to the curved portion to which one end is connected (see FIG. 4B).
c) When both ends are connected to the curved portion as tangent lines The average direction of the arc surface normal of the curved portion to which both ends are connected is defined as a normal line (see FIG. 4B).
d) When one end is connected to the bending R portion, the outer product is obtained from the two side directions sandwiching the bending R portion and set as the arc surface normal.
e) When both ends are connected to the bend R portion The average direction of the outer product direction obtained from the two side directions sandwiching both bend R portions is the normal line.

The movement point calculation means 7 guides the slave division point x (hereinafter referred to as “movement point x1”) at the position after movement of the secondary reinforcing bar B through the following processing (see FIG. 6).
Step 1: An intersection point (hereinafter referred to as “designated division point y”) between the core wire a of the designated reinforcing bar A and the deformation surface S2 is derived.
Step 2: A straight line (hereinafter referred to as “moving straight line”) connecting the subdivision point x and the designated division point y is derived.
Step 3: A point of intersection of the moving straight line and the outer edge of the designated reinforcing bar A is derived, and a point further separated by a radius of the slave reinforcing bar B in the moving direction of the designated reinforcing bar A from the moving direction side intersection (moving point x1) (See FIG. 6).

The deformation base point calculation means 8 derives a specified length through, for example, the following processing (see FIG. 7).
Step 1: A distance d between the moving point x1 and the subdivision point x is derived.
Step 2: The allowable angle α is set to an arbitrary value from 0 degrees to 30 degrees.
Step 3: Based on the distance d and the allowable angle α, the length obtained by d / tan α is set as a specified length.
The allowable angle refers to the bending angle of the secondary reinforcing bar B at the deformation base point p allowed when the secondary reinforcing bar B that interferes with the movement of the designated reinforcing bar A is deformed, and the allowable angle α is zero. In this case, the length is infinite.

Further, the deformation base point calculation means 8 provides the deformation base point p on both sides sandwiching the secondary division point x from the prescribed length obtained on the left, for example, through the following processing, and sets the side between x-p as the driven part. (See FIG. 7A).
When there is a bending R portion within the specified length, the nearest end of the bending R portion is set as the deformation base point p, and the side between xp is set as the driven portion (see FIG. 7B).
Also, if any side length sandwiching the subdivision point x is shorter than the specified length and the deformation base point p cannot be provided, the deformation base point is indefinite, and the side between the x-end is used as the driven portion (see FIG. 7 (C)).

The reinforcing bar deforming means 9 includes a circular arc part forming means that forms a circular arc part at a portion bent by the reinforcing bar deforming means 9 to form a new bent R part (hereinafter referred to as “new bent R part”).
The arc portion forming means obtains a cross-sectional line shape of the designated reinforcing bar A from the intersection point y between the skin of the designated reinforcing bar A and the deformation surface S2, and a new bend R portion (arc portion) set to a desired radius on the movement vector. Is provided (see FIG. 10).

Subsequently, the following processing is performed as appropriate based on the relationship between the line length of the driven portion to be subjected to the movement processing or deformation processing and the specified length (see FIG. 8).
(1) When the line length of the driven portion is less than the specified length, the driven portion is translated in the moving linear direction, and the tangent line between the driven portion and the new bending R portion (arc portion) is guided (FIG. 8A). reference).
(2) When the line length of the driven part has a specified length The rotational part is rotated in the moving linear direction with the deformation base point p as the rotation axis, and a tangent to the new bending R part (arc part) is guided (FIG. 8B )reference).
When the driven part that performs rotational movement is configured by connecting a plurality of line segments, a vector that connects the subdivision point x and the contact point of the tangent line is obtained, and each node of the line segment group is determined in the full length of the vector. A deformation process of moving to a position proportional to the distance from the deformation base point p is performed (see FIG. 9).
v2 = x1-x
v1 = ((L0 + L1) / L) × v2
v0 = (L0 / L) × v2
When the deformation base point p before deformation is on the bending R portion, the deformation base point p (end point of the driven portion) is moved to the position of the contact point between the driven portion after deformation and the bending R portion. (Refer to FIG. 8C), the graphic data of the reinforcing bar after the deformation process is updated through the process of making the contact point (deformation base point p) and the subsequent arc part of the bending R part.

Along with the movement of the designated reinforcing bar A, for example, a series of curved parts having no bending R part circulates, and a plurality of secondary dividing points x are generated for one secondary reinforcing bar. When the specified lengths before and after are overlapped with each other, with respect to the movement of each division point x, the curve part of the secondary reinforcing bar B before correction is associated with each movement, for example, the normal of each point of the curve part is Deformation (involute curving) can be performed so as to be a tangent of a fixed circle set inside the sub-rebar before correction (see FIGS. 15 and 16).
At this time, the base point of the deformation is an adjacent secondary division point x separated from the secondary division point x before correction by the circumference of the secondary reinforcing bar B (hereinafter referred to as “ring length”), or from the secondary division point before correction. The points can be long / 2 apart.

When there is another reinforcing bar (hereinafter referred to as “re-sub-rebar C”) crossing the deformation surface S2 of the secondary reinforcing bar B guided by the movement of the specified reinforcing bar A, the secondary reinforcing bar is present. B is regarded as a new designated reinforcing bar A, and the processes of the interference detection means 1 and the interference correction means 2 are repeated for all the repetitive reinforcing bars C intersecting the deformation surface S2 (new movement surface) (see FIG. 17). .
At that time, depending on the bar arrangement situation, the secondary reinforcing bar B (re-repetitive reinforcing bar C, etc.) for the new designated reinforcing bar A further overlaps with the new designated reinforcing bar A, so that the processing falls into an infinite loop. Since there is a possibility, it is necessary to predetermine the upper limit to be regarded as a new designated reinforcing bar A as n generations.

In the above processing, a new moving surface (the deformed surface S2) of the new designated reinforcing bar A (the secondary reinforcing bar B) is defined through the following processing.
That is, the secondary split point x of the secondary reinforcing bar B before correction, the start and end points of the bending R portion and the nodes existing within the specified length, and the moving point x1, the bending R portion or the new bending R of the secondary reinforcing bar B after correction. Facing the start and end points, nodes existing within the specified length, and deformation base points p (hereinafter referred to as “original points P0, a, b,..., F, g, h, i, P1 (P2)”). Points (hereinafter referred to as “face-to-face points”) are created in the secondary reinforcing bar B before and after the correction, and the original points P0, a, b,..., F, g, h, i, P1 (P2) and A quadrilateral connecting the facing points is created, and a plurality of triangles are created by drawing one diagonal line so as not to share a point for each quadrangle (see FIGS. 18 to 20).

The facing points are derived by performing the following processing on the secondary reinforcing bars B before and after correction (see FIG. 18).
(1) The length L1 between the start and end of the secondary reinforcing bar B after the correction and the length L0 between the start and end of the secondary reinforcing bar B before the correction with the same start and end are derived, and the secondary reinforcing bar before and after the correction The distance from the starting end of B to each point defining the secondary reinforcing bar B is derived.
(2) The ratio of the distance to each point defining the secondary reinforcing bar B with respect to the length L1 between the start and end (hereinafter referred to as “point ratio”) is derived.
(3) Integrate (match) the point ratios of the corresponding reinforcing bar B before and after correction.
(4) Leave only one except one of the overlapping point ratios due to the integration.
(5) Face-to-face points are set at the positions of the respective point ratios integrated with respect to the corresponding reinforcing bar B before and after correction, and without the original points.

Through the above processing, the secondary reinforcing bars B before and after the correction have the same number of nodes, and form a triangle by connecting the mutual contacts.
As a specific example, the ratio of each of the node a, the node b, and the node c is as follows.
a = (l1 / L0) × L1,
b = ((l1 + l2) / L0) × L1,
c = (l1 / L0) × L1,
....

When the moving surface S1 of the specified reinforcing bar A is in contact with the bending R portion of the secondary reinforcing bar B, the following processing can be performed in the following two cases.
(1) When the moving surface S1 crosses the secondary reinforcing bar B (see FIG. 21)
(2) When the moving surface S1 does not cross the secondary reinforcing bar B (see FIG. 22)
The center of the bending R part after the movement is set on the movement line of the specified reinforcing bar (see FIG. 21) or at the position of the length of the movement line from the center of the bending R part before the movement (see FIG. 22).

  In this example, the interference correction means 2 uses the position data of the core wire b of the secondary reinforcing bar B before correction as the moving point x1 for the intersecting portion generated in the secondary reinforcing bar B as the designated reinforcing bar A moves. A data update means 10 is provided for updating the position data of the apexes constituting the core wire b of the arc portion generated between the elements such as the front driven portion and the rear driven portion that are paired with the core interposed therebetween.

  The secondary reinforcing bar B whose position data of the core wire b has been updated by the data updating means 10, the image editing means, the graphic data searched by the data searching means, together with the frame related to the graphic data, It outputs as the image of the said secondary reinforcing bar B to which the skin was attached.

Hereinafter, a means for avoiding interference or the like when the “deformation” switch is ON will be described.
In this example, as a function of editing or correcting the reinforcing bar data, a designation that causes interference with one or more secondary reinforcing bars B or poor linkage with one or multiple secondary reinforcing bars B as a result of moving the specified reinforcing bar A It is an interference avoiding means for correcting the position data of the reinforcing bar A so as to avoid the interference or poor linkage.

[Interference avoidance measures]
The avoidance means for interference, etc. in this example specifies the attributes of the secondary reinforcing bar B that causes interference or poor linkage with the specified reinforcing bar A based on the ID of the specified reinforcing bar A as the specified reinforcing bar A moves, A part of the position data of the specified reinforcing bar A is changed to position data that can avoid interference, and related graphic data that changes accordingly is changed.
The avoidance means such as interference in this example includes the interference detection means 1 for detecting the presence or absence of interference with the secondary reinforcing bar B accompanying the movement of the specified reinforcing bar A, and a part of the specified reinforcing bar A. The correction means 2 for interference etc. for moving the position where a part of the reinforcing bar A should be provided is provided (see FIG. 23).

  By moving the stirrup (designated rebar A) in the longitudinal direction of the main reinforcing bar arranged inside, interference or poor linkage occurs with the main reinforcing bar (secondary reinforcing bar B) arranged inside the stirrup. In the positional relationship between the two, excessive separation, internal / external reversal or superposition occurs, but here, explanation will be given based on the case where excessive separation and internal / external reversal occur among them (see FIG. 23).

<Interference detection means>
The detection means 1 such as interference is based on the movement information detecting means 4 that guides the entire movement path formed as the specified reinforcing bar A is moved as one moving surface S1, and the specified reinforcing bar based on the specified information. The secondary reinforcing bar B that is linked to A and detects the secondary reinforcing bar B that intersects the moving surface S1 accompanying the movement of the designated reinforcing bar A or is separated from the designated reinforcing bar A after the movement by a predetermined distance or more. The problem reinforcing bar detecting means 11, the deformation surface detecting means 6 for guiding the deformation surface S3 along which the dividing point X of the specified reinforcing bar A moves in accordance with the movement of the specified reinforcing bar A, and the slave bar B intersecting the deformation surface S3. And the intersection detection means 5 for guiding the intersection of the secondary reinforcing bar B is combined (see FIG. 24 or FIG. 25).

The problem reinforcing bar detection means 11 verifies the presence of a reinforcing bar that causes interference or poor linkage with the movement of the designated reinforcing bar A.
In this example, the deformed surface detecting means 6 is a plane that includes stirrup from the shape of the designated reinforcing bar A according to the above process when a reinforcing bar that interferes with the movement of the designated reinforcing bar A or a linkage failure is detected. And the said deformation | transformation surface S3 which consists of the extension surface is produced about each before and behind the movement of the said designated reinforcing bar A. As shown in FIG.
The intersection detection means 5 performs a process of creating a cut surface of the secondary reinforcing bar B that intersects the deformed surface S3 and storing position data of the reinforcing bar where the cut surface is created (see FIG. 26).

<Correction correction means>
In this example, the interference correction unit 2 includes a dividing point calculating unit 12 for deriving the position of the dividing point X, a deformation base point calculating unit 8 for deriving the deformation base point p of the secondary reinforcing bar, and the movement of the designated reinforcing bar A. Reinforcing bar deformation means 9 for deforming the specified reinforcing bar A so as to avoid interference with the secondary reinforcing bar or poor linkage, and data updating means 10 for updating the position data of the specified reinforcing bar A immediately before retraction with the position data after retraction. (See FIG. 24).

The dividing point calculation means 12 superimposes the deformation surfaces S3 before and after the movement, obtains a movement straight line connecting the centers of the cut planes created before and after the movement (hereinafter referred to as “cutting points”), and designates the movement straight line and the designation after the movement. The intersection (division point X) with the reinforcing bar A is obtained (see FIG. 23).
The division point X obtained in this way is regarded as the secondary division point x of the secondary reinforcing bar B in the interference avoidance process when the “deformation” switch = off, and is the same as when the secondary reinforcing bar B is moved or deformed. In addition, by performing the processing of the deformation base point calculation means 8, the reinforcing bar deformation means 9 and the data update means 10 in the interference correction means 2, the interference with the secondary reinforcing bar B accompanying the movement of the specified reinforcing bar A is automatically avoided. To do.

The specifics are listed below in order.
(1) The cross section position T0 of the main muscle is obtained from the S3 (P0) plane of the stirrup before the movement.
(2) The cross section position T1 of the main muscle is obtained from the S3 (P1) plane of the stirrup after movement.
(3) S3 (P0) and S3 (P1) are moved from P0, upV0, S3 (P0) normal and P1, upV1, S3 (P1) normal so as to overlap at an arbitrary position.
(4) A moving straight line connecting T0 to T1 is obtained.
(5) The intersection of the moving straight line and the stirrup core axis a is obtained, and is regarded as a secondary division point x when the secondary reinforcing bar B is moved or deformed.

  The correction means 2 for interference in this example makes a pair of the position data of the core wire a of the specified reinforcing bar A before correction with the division point X of the specified reinforcing bar A after correction and the division point X in between. Data updating means 10 is provided for updating the position data of the apexes constituting the core line a of the arc portion generated between the elements such as the front driven portion and the rear driven portion.
