Description

Technical Field

[0001] This invention relates to the field of test bench technology, and in particular to a brake hose material identification bench and method. Background Technology

[0002] With the development of automotive technology, refined design has become increasingly important, leading to significant constraints on layout space, especially for brake hoses. Due to their complex material and structural properties, the layout of brake hoses must not only absorb changes in distance between fixed points during suspension movement but also avoid interference with other components. Therefore, accurately simulating their stress conditions and optimizing their length while reducing stress and strain is crucial. Accurate stress simulation requires correctly identifying the material properties of the brake hose, including its elastic modulus, Poisson's ratio, and density.

[0003] Chinese Patent Publication No. CN113125171B discloses a brake hose suspension durability testing system, including a test frame and an inclined operating platform for controlling the operation of the testing system. A workbench is connected to the top of the test frame, and the workbench is equipped with at least four sets of pipe head positioning fixtures for fixing one end of the brake hose. A locking component and a pipe tail positioning fixture connected to the side wall of the locking component for fixing the end of the brake hose away from the pipe head positioning fixture are also provided on the top of the workbench. However, this solution only tests the durability of the brake hose and cannot identify the material properties of the brake hose. Summary of the Invention

[0004] Therefore, the present invention provides a brake hose material identification stand and method to overcome the problem of low brake hose material identification efficiency in the prior art.

[0005] To achieve the above objectives, the present invention provides a brake hose material identification platform, comprising,

[0006] Fixed end, used to secure one end of the brake hose;

[0007] A connecting member for connecting the sixth and seventh pipe trusses, which is connected to the lower end of the seventh pipe truss and to the middle end of the sixth pipe truss.

[0008] The pipe truss assembly, which serves as the support part of the platform and is used to build the framework of the platform, is composed of thirteen pipe trusses.

[0009] The truss adjustment assembly includes several truss adjusters, each truss adjuster is disposed at the connection between trusses, the truss adjuster is embedded in the connected pipe truss, and can slide along the slide groove of the pipe truss to adjust the relative position of the two connected pipe trusses.

[0010] A truss adjustment mechanism, located on the upper part of the platform, is used to adjust the moving end of the brake hose, fixing and moving the brake hose during the identification process.

[0011] Furthermore, one end of the brake hose is fixed to the fixed end of the platform to keep one end of the brake hose fixed, and the end of the brake hose away from the fixed end is connected to the seventh pipeline truss. The end of the brake hose connected to the seventh pipeline truss is set as the moving end of the brake hose, and the brake hose is moved through the seventh pipeline truss to control the brake hose to form different postures.

[0012] Further, the pipeline truss assembly includes: a first pipeline truss connected to a second pipeline truss via a first truss adjuster; a second truss adjuster located at the end of the second pipeline truss away from the first truss adjuster; the second pipeline truss connected to a fifth pipeline truss via the second truss adjuster; the upper end of the fifth pipeline truss fixedly connected to a fourth pipeline truss; a third truss adjuster located at one end of the fourth pipeline truss; the fourth pipeline truss connected to a third pipeline truss via the third truss adjuster; a fourth truss adjuster located at the end of the fourth pipeline truss away from the third truss adjuster; the fourth pipeline truss connected to a tenth pipeline truss via the fourth truss adjuster; a fifth truss adjuster located at the upper end of the fifth pipeline truss away from the fourth pipeline truss; and the fifth pipeline truss connected to a thirteenth pipeline truss via the fifth truss adjuster. One side of the thirteenth pipe truss is connected to the bottom surface of the sixth pipe truss via the sixth truss adjuster. The thirteenth pipe truss also has a seventh truss adjuster on the side away from the sixth truss adjuster. The thirteenth pipe truss is connected to the eighth pipe truss via the seventh truss adjuster. The eighth pipe truss has an eighth truss adjuster on one side and is connected to the ninth pipe truss via the eighth truss adjuster. The thirteenth pipe truss has a ninth truss adjuster above it and is connected to the eleventh pipe truss via the ninth truss adjuster. The eleventh pipe truss has a tenth truss adjuster at its upper end and is connected to the twelfth pipe truss via the tenth truss adjuster. The twelfth pipe truss has an eleventh truss adjuster on one side and is connected to the fixed end via the eleventh truss adjuster.

[0013] Furthermore, the truss adjustment mechanism consists of the connecting member, the sixth pipeline truss, and the seventh pipeline truss. The truss adjustment mechanism controls the moving end of the brake hose to move along the direction of the sixth pipeline truss, the direction of the eighth pipeline truss, and the direction of the thirteenth pipeline truss, respectively, so as to adjust the brake hose to form different postures.

[0014] On the other hand, the present invention also provides a method for identifying brake hose material identification benches, including,

[0015] Step S1: Clamp the target brake hose onto the test stand;

[0016] Step S2: The target brake hose is adjusted in attitude by the truss adjustment mechanism, and the target brake hose after attitude adjustment is scanned and measured to obtain the pipeline status data of the target brake hose under each attitude.

[0017] Step S3: Calculate the material properties of the target brake hose under each attitude based on the pipeline state data under each attitude.

[0018] Step S4: Compare the material properties of the target brake hose in the reverse posture with the preset material properties and calculate the error value. When the error value is greater than the standard error, change the posture of the brake hose and recalculate the material properties until the error value meets the requirements.

[0019] Furthermore, during the clamping process in step S1, the support sleeve of the target brake hose is removed to obtain the natural tubing after removal, and the target brake hose is clamped on the test bench according to its actual position in the actual vehicle.

[0020] Further, in step S2, during attitude adjustment, a spatial rectangular coordinate system is set, and the truss adjustment mechanism is controlled to adjust the attitude of the target brake hose according to the spatial rectangular coordinate system. Here, the direction along the sixth pipeline truss is set as the X-axis, and the end of the sixth pipeline truss closest to the third pipeline truss is defined as the positive direction of the X-axis. The direction along the thirteenth pipeline truss is set as the Y-axis, and the end of the thirteenth pipeline truss closest to the eleventh pipeline truss is defined as the positive direction of the Y-axis. The direction along the eighth pipeline truss is set as the Z-axis, and the end of the eighth pipeline truss furthest from the thirteenth pipeline truss is defined as the positive direction of the Z-axis.

[0021] Further, in step S2, a first posture is obtained by scanning the initial posture of the target brake hose clamped on the test bench. A second posture is obtained by moving the moving end of the target brake hose a distance B along the positive X-axis using the truss adjustment mechanism. After obtaining the second posture, the initial posture is returned. A third posture is obtained by moving the moving end of the target brake hose a distance B along the negative X-axis using the truss adjustment mechanism. A fourth posture is obtained by moving the moving end of the target brake hose a distance B along the positive Z-axis using the truss adjustment mechanism. A fifth posture is obtained by moving the moving end of the target brake hose a distance B along the positive X-axis using the truss adjustment mechanism. A sixth posture is obtained by moving the moving end of the target brake hose a distance B along the negative X-axis using the truss adjustment mechanism. Here, B is a preset distance, 0mm < B ≤ 200mm.

[0022] Furthermore, in step S3, the actual material properties are calculated based on the six postures of the target brake hose, and the preset material properties are theoretically calculated by obtaining the six postures of the target brake hose under ideal conditions. The material properties include elastic modulus, Poisson's ratio, and density. The ideal state refers to the state of the target brake hose when it is used without wear.

[0023] Furthermore, in step S4, the reverse posture refers to the posture obtained when the target brake hose moving end is moved by the truss adjustment mechanism, causing the brake hose moving end to rotate counterclockwise relative to the fixed end. The reverse posture includes the third posture and the sixth posture.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the fixed end of the brake hose is fixed to the platform by clamping, so as to maintain stability during the material identification process of the brake hose, thereby accurately identifying the material and improving the material identification efficiency of the brake hose; the connecting member connects the sixth pipeline truss and the seventh pipeline truss, so that the brake hose can move through the sixth pipeline truss and the seventh pipeline truss, thereby performing material identification and improving the material identification efficiency of the brake hose; the pipeline truss forms the frame part of the platform to clamp the brake hose and move it on the platform, thereby improving the material identification efficiency of the brake hose; the truss adjustment assembly is set at the connection between each truss, so that the truss can be moved through the truss adjuster, thereby improving the material identification efficiency of the brake hose.

[0025] In particular, the truss adjustment mechanism includes the connecting member, the sixth pipeline truss, and the seventh pipeline truss. The truss adjustment mechanism can move the moving end of the brake hose in space to obtain the material properties of the brake hose and improve the material identification efficiency.

[0026] In particular, the target brake hose is clamped on a test bench in the actual position in a real vehicle to simulate the actual state of the brake hose, and the material of the brake hose is identified in the actual state, thereby further improving the material identification efficiency of the brake hose.

[0027] In particular, the direction of the truss adjustment mechanism to move the brake hose is set as the X-axis, Y-axis and Z-axis respectively, thereby adding a rectangular coordinate system to the process of brake hose material identification on the test bench, and further improving the material identification efficiency of the brake hose.

[0028] In particular, step S2 obtains six postures of the brake hose by moving the brake hose, simulating the actual posture of the brake hose, and then identifies the brake hose material based on the six postures, thereby improving the efficiency of brake hose material identification.

[0036] Fixed end 14 is used to fix one end of the brake hose 17;

[0037] The connecting member 15 is used to connect the sixth pipe truss 6 and the seventh pipe truss 7. It is connected to the lower end of the seventh pipe truss 7 and to the middle end of the sixth pipe truss 6.

[0038] The pipe truss assembly, which serves as the support part of the platform and is used to build the framework of the platform, is composed of thirteen pipe trusses.

[0039] The truss adjustment assembly includes several truss adjusters, each truss adjuster is disposed at the connection between trusses, the truss adjuster is embedded in the connected pipe truss, and can slide along the slide groove of the pipe truss to adjust the relative position of the two connected pipe trusses.

[0040] A truss adjustment mechanism, located on the upper part of the platform, is used to adjust the moving end of the brake hose 17, and to fix and move the brake hose 17 during the identification process of the brake hose.

[0041] Specifically, the fixed end of the brake hose is clamped to fix one end of the brake hose to the platform to maintain stability during the material identification process, thereby accurately identifying the material and improving the material identification efficiency of the brake hose. The connecting member connects the sixth and seventh pipe trusses, allowing the brake hose to move through the sixth and seventh pipe trusses for material identification, thus improving the material identification efficiency of the brake hose. The pipe trusses form the frame of the platform to clamp the brake hose and move it on the platform, thereby improving the material identification efficiency of the brake hose. The truss adjustment assembly is located at the connection between the trusses to allow the trusses to move through the truss adjuster, thereby improving the material identification efficiency of the brake hose.

[0042] Specifically, one end of the brake hose 17 is fixed to the fixed end 14 of the platform to keep one end of the brake hose 17 fixed. The end of the brake hose 17 away from the fixed end 14 is connected to the seventh pipeline truss 7. The end of the brake hose 17 connected to the seventh pipeline truss 7 is set as the moving end of the brake hose 17. The brake hose 17 is moved by the seventh pipeline truss 7 to control the brake hose 17 to form different postures.

[0043] Specifically, the pipeline truss assembly includes a first pipeline truss 1, which is connected to a second pipeline truss 2 via a first truss adjuster 18. A second truss adjuster 19 is provided at the end of the second pipeline truss 2 away from the first truss adjuster 18. The second pipeline truss 2 is connected to a fifth pipeline truss 5 via the second truss adjuster 19. The upper end of the fifth pipeline truss 5 is fixedly connected to a fourth pipeline truss 4.

The fourth pipeline truss 4 has a fourth truss adjuster (not shown in the figure) at its end away from the third truss adjuster 20. The fourth pipeline truss 4 is connected to the tenth pipeline truss 10 via the fourth truss adjuster. The upper end of the fifth pipeline truss 5 has a fifth truss adjuster (not shown in the figure) on its side away from the fourth pipeline truss 4.

One side of truss 13 is connected to the bottom surface of the sixth pipeline truss 6 via the sixth truss adjuster (not shown in the figure). The thirteenth pipeline truss 13 also has a seventh truss adjuster (not shown in the figure) on the side away from the sixth truss adjuster. The thirteenth pipeline truss 13 is connected to the eighth pipeline truss 8 via the seventh truss adjuster. The eighth pipeline truss 8 has an eighth truss adjuster 21 on one side, and the eighth pipeline truss 8 is connected to the ninth pipeline truss 9 via the eighth truss adjuster 21. The thirteenth pipeline... A ninth truss adjuster is provided above the truss 13. The thirteenth pipeline truss 13 is connected to the eleventh pipeline truss 11 through the ninth truss adjuster. The eleventh pipeline truss 11 is provided with a tenth truss adjuster (not shown in the figure) at its upper end. The eleventh pipeline truss 11 is connected to the twelfth pipeline truss 12 through the tenth truss adjuster. The eleventh truss 12 is provided with an eleventh truss adjuster on one side. The twelfth pipeline truss 12 is connected to the fixed end 14 through the eleventh truss adjuster.

[0044] Specifically, the truss adjustment mechanism consists of the connecting member 15, the sixth pipeline truss 6, and the seventh pipeline truss 7. The truss adjustment mechanism controls the moving end of the brake hose 17 to move along the direction of the sixth pipeline truss 6, the direction of the eighth pipeline truss 8, and the direction of the thirteenth pipeline truss 13, respectively, so as to adjust the brake hose 17 to form different postures.

[0045] Specifically, the truss adjustment mechanism includes the connecting member, the sixth pipeline truss, and the seventh pipeline truss. The truss adjustment mechanism can move the movable end of the brake hose in space to obtain the material properties of the brake hose and improve material identification efficiency. It is understood that this embodiment does not specifically limit the direction in which the truss adjustment mechanism moves the brake hose; those skilled in the art can freely set it, as long as it satisfies the requirement for the brake hose to move in space.

[0046] Please see Figure 2 The method for identifying brake hose material includes,

[0047] Step S1: Clamp the target brake hose onto the test stand;

[0048] Step S2: The target brake hose is adjusted in attitude by the truss adjustment mechanism, and the target brake hose after attitude adjustment is scanned and measured to obtain the pipeline status data of the target brake hose under each attitude.

[0049] Step S3: Calculate the material properties of the target brake hose under each attitude based on the pipeline state data under each attitude.

[0050] Step S4: Compare the material properties of the target brake hose in the reverse posture with the preset material properties and calculate the error value. When the error value is greater than the standard error, change the posture of the brake hose and recalculate the material properties until the error value meets the requirements.

[0051] Specifically, during the clamping process in step S1, the support sleeve of the target brake hose is removed to obtain the natural tubing after removal, and the target brake hose is clamped on the test bench according to its actual position in the actual vehicle.

[0052] Specifically, the target brake hose is clamped on a test bench in the actual position in a real vehicle to simulate the actual state of the brake hose. The material of the brake hose is then identified based on this actual state, further improving the material identification efficiency of the brake hose.

[0053] Specifically, in step S2, during attitude adjustment, a spatial rectangular coordinate system is set, and the truss adjustment mechanism is controlled to adjust the attitude of the target brake hose according to the spatial rectangular coordinate system. Here, the direction along the sixth pipeline truss 6 is set as the X-axis, and the end of the sixth pipeline truss 6 near the third pipeline truss 3 is defined as the positive direction of the X-axis. The direction along the thirteenth pipeline truss 13 is set as the Y-axis, and the end of the thirteenth pipeline truss 13 near the eleventh pipeline truss 11 is defined as the positive direction of the Y-axis. The direction along the eighth pipeline truss 8 is set as the Z-axis, and the end of the eighth pipeline truss 8 away from the thirteenth pipeline truss 13 is defined as the positive direction of the Z-axis.

[0054] Specifically, the directions of movement of the brake hose by the truss adjustment mechanism are set as the X-axis, Y-axis, and Z-axis, respectively. This incorporates a Cartesian coordinate system during the brake hose material identification process on the test bench, further improving the efficiency of brake hose material identification. It is understood that this embodiment does not specifically limit the movement directions corresponding to the X-axis, Y-axis, and Z-axis; those skilled in the art can freely set them, as long as they accurately describe the movement process. For example, the direction of the sixth pipeline truss can be set as the Y-axis.

[0055] In step S2, the first posture is obtained by scanning the initial posture of the target brake hose clamped on the test stand. The second posture is obtained by moving the moving end of the target brake hose along the positive X-axis by a distance B through the truss adjustment mechanism. After obtaining the second posture, the target brake hose returns to the initial posture. The third posture is obtained by moving the moving end of the target brake hose along the negative X-axis by a distance B through the truss adjustment mechanism. The fourth posture is obtained by moving the moving end of the target brake hose along the positive Z-axis by a distance B through the truss adjustment mechanism. The fifth posture is obtained by moving the moving end of the target brake hose along the positive X-axis by a distance B through the truss adjustment mechanism. The sixth posture is obtained by moving the moving end of the target brake hose along the negative X-axis by a distance B through the truss adjustment mechanism. Here, B is a preset distance, 0mm < B ≤ 200mm.

[0056] Specifically, step S2 involves moving the brake hose to obtain six postures of the brake hose, simulating its actual posture, and then using these six postures to identify the brake hose material, thereby improving the efficiency of brake hose material identification. It is understood that this embodiment does not limit the number of brake hose postures; those skilled in the art can freely set them, as long as the required number of postures for brake hose material identification is met. For example, in the fourth posture, the target brake hose moving end can be moved a distance B in the positive Y-axis direction using a truss adjustment mechanism to obtain the seventh posture.

[0057] Specifically, in step S3, the actual material properties are calculated based on the six postures of the target brake hose. The preset material properties are theoretically calculated by obtaining the six postures of the target brake hose under ideal conditions. The material properties include elastic modulus, Poisson's ratio, and density. The ideal state refers to the state of the target brake hose when it is used without wear.

[0058] Specifically, in step S3, the calculation system is used to calculate the pipeline state data under each attitude. It is understood that this embodiment does not specifically limit the calculation system in step S3. Those skilled in the art can set it freely, as long as it can calculate the pipeline state of the brake hose under each attitude. For example, the calculation system can be set to the teapipe module in CATIA software.

[0059] Specifically, in step S4, the reverse posture refers to the posture obtained when the target brake hose moving end is moved by the truss adjustment mechanism, causing the brake hose moving end to rotate counterclockwise relative to the fixed end 14. The reverse posture includes the third posture and the sixth posture.

[0060] Specifically, in step S4, when recalculating the material properties, this embodiment can re-scan and measure the brake hose and calculate the material properties by increasing the posture of the brake hose. It is worth noting that while changing the posture of the brake hose, the accuracy of the calculation can also be improved by checking whether the platform moves or deforms during scanning and the influence of the scanned point cloud on the calculation. At the same time, those skilled in the art can also consider the influence of other factors on the calculation. This embodiment does not make specific limitations, such as considering the reverse pipeline deviation problem when reversing.

[0061] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
