Description

Technical Field

[0001] This invention relates to the field of intelligent testing equipment for ring-shaped composite materials, specifically to an intelligent testing fixture and method for testing the strength, durability, and bilateral balance of ring-shaped composite materials. The ring-shaped composite materials include, but are not limited to, treadmill belts, industrial conveyor belts, and other similar materials. These materials typically consist of a multi-layered composite structure comprising a rubber matrix, fiber reinforcement layers (such as polyester fiber, nylon fiber, steel wire rope core, etc.), and a surface coating, possessing functional characteristics such as load-bearing, transmission, and wear resistance. Background Technology

[0002] Currently, testing technology for ring composite materials mainly focuses on detecting single performance indicators, and most testing equipment lacks intelligent control functions. Chinese patent CN103512692B discloses a treadmill belt tension testing device. This device detects the tension of the ring composite material using a force sensor and measures the elongation of the material by the distance a displacement pointer moves, enabling the testing of both static and dynamic elongation of the ring composite material. Additionally, existing technologies include durability testing machines for ring composite materials that apply periodic loads to the material using impact wheels to simulate wear during long-term use and assess the service life of the ring composite material. However, these devices generally lack intelligent real-time monitoring and automatic adjustment functions.

[0003] Although existing testing techniques for ring composite materials are relatively mature in some aspects, they still have the following significant shortcomings:

[0004] For example, existing testing equipment can usually only test a single performance index of ring composite materials, and cannot simultaneously perform comprehensive evaluation of multiple properties such as strength testing and durability testing.

[0005] Furthermore, existing technologies generally overlook the problem of imbalance on both sides of the annular composite material. Different degrees of material fatigue and strength reduction may occur on the left and right sides of the annular composite material, leading to problems such as displacement and vibration during operation.

[0006] Furthermore, strength testing and durability testing of ring composite materials usually need to be carried out separately, which is inefficient and cannot obtain data on the correlation changes of various performance parameters of the material during long-term use.

[0007] Furthermore, most existing testing methods rely on manual observation and adjustment, lacking intelligent real-time monitoring and automatic compensation functions, and thus cannot achieve intelligent response and automatic adjustment to changes in the strength of ring composite materials.

[0008] Therefore, it is necessary to develop an intelligent integrated testing fixture that can simultaneously perform strength testing and bilateral balance testing of ring composite materials to improve the quality control level of ring composite material products. Summary of the Invention

[0009] The purpose of this invention is to provide an intelligent durability and bilateral balance testing fixture for ring composite materials, so as to solve the problem that the existing ring composite material testing cannot simultaneously detect the difference in fatigue strength between the two sides of the material, and realize the intelligent synchronous performance of ring composite material durability testing and bilateral balance detection.

[0010] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0011] A smart testing fixture for the strength, durability, and bilateral balance of a ring-shaped composite material includes: a test workbench serving as a support platform for the testing fixture; a running drive device for driving the ring-shaped composite material to simulate actual operating conditions; and a tension stabilizing structure for maintaining the stable operation of the ring-shaped composite material.

[0012] Notably, it also includes:

[0013] The intelligent synchronous testing device includes: a tension roller assembly, comprising multiple tension rollers, used to form a wrapping contact with the annular composite material to transmit the material deformation effect; two balancing linkage mechanisms, respectively located on both sides of the annular composite material, each balancing linkage mechanism cooperating with a lever linkage assembly and a force application control assembly to independently respond to the relaxation status of its corresponding side of the annular composite material and to perform intelligent compensation adjustment; and a synchronous detection structure for real-time monitoring of the motion parameters of the two balancing linkage mechanisms.

[0014] The vibration and warping detection mechanism includes: detection frames symmetrically arranged on both sides of the annular composite material. Each detection frame includes a support and contact sensing elements distributed on the side of the support. The sensing elements are embedded in the edge of the annular composite material. The deformation degree of the sensing elements is used to intelligently monitor the operating status and warping of the annular composite material, and to provide intelligent control signals for the start and stop of the balancing linkage mechanism.

[0015] Furthermore, the tensioning roller assembly includes three tensioning rollers arranged in an inverted isosceles triangle shape, namely a movable tensioning roller located in the middle position and fixed tensioning rollers located on both sides. The annular composite material passes through the three tensioning rollers in sequence and wraps around the lower half-curved surface of the movable tensioning roller. This inverted isosceles triangle distribution structure can maximize the contact area between the annular composite material and the movable tensioning roller, thereby improving the deformation transmission effect and detection sensitivity.

[0016] Furthermore, the balancing linkage mechanism includes an integrated shaft frame and a lever linkage assembly. The lever linkage assembly includes an unequal diameter balancing component as a lever. The unequal diameter balancing component includes a lever arm and an unequal diameter wheel. The unequal diameter wheel is offsetly hinged to a hinge shaft that serves as the fulcrum of the lever. This lever structure can amplify the minute relaxation changes of the annular composite material into significant mechanical displacement, thereby achieving intelligent and high-precision measurement.

[0017] Furthermore, the integrated shaft frame is provided with a limiting groove, and the hinge shaft is slidably connected in the limiting groove. When the lever arm rotates downward, the distance between the end of the unequal diameter wheel that abuts against the top plate of the integrated shaft frame and the center of the hinge shaft increases linearly. This linearly increasing design ensures a linear correspondence between the torque change and the relaxation degree of the annular composite material, thereby achieving accurate quantitative measurement.

[0018] Furthermore, the balancing linkage mechanism also includes a force control component, which includes a wire rope and a constant force output device. One end of the wire rope is connected to the unequal diameter balancing component, and the other end is wound around the constant force output device. The constant force output device can provide a stable external force to ensure the consistency and repeatability of the applied force during the test, and can achieve automatic adjustment in conjunction with the intelligent control system.

[0019] Furthermore, a sliding sleeve is fitted at the end of the movable tension roller, and the sliding sleeve is slidably connected to the integrated shaft frame. This sliding sleeve structure ensures the stable movement of the movable tension roller during the intelligent adjustment process and avoids test errors caused by unstable movement.

[0020] Furthermore, the synchronous detection structure includes a horizontal frame, a horizontal support box, and a measuring instrument. Steel wire ropes pass through both ends of the horizontal frame and are both placed on the upper end of the horizontal support box. A displacement sensor is installed inside the horizontal support box, and the measuring instrument is installed in the middle position on the upper end of the horizontal frame. Through the cooperation of the displacement sensor and the measuring instrument, the displacement and angle changes of the two-sided balancing linkage mechanism can be obtained simultaneously, realizing synchronous detection of two parameters.

[0021] Furthermore, the measuring instrument uses a level or angle gauge, which can accurately measure the tilt angle of the horizontal frame, intuitively reflecting the difference in deformation on both sides of the annular composite material, and enabling real-time analysis in conjunction with the data processing system.

[0022] Furthermore, the contact sensing element is a brush, which has good flexibility and sensitivity, and can keenly sense the subtle vibrations and edge warping changes of the annular composite material edge, providing accurate status feedback signals for the intelligent control system.

[0023] Furthermore, the running drive device includes a drive motor, a synchronous belt, a drive roller, and a driven roller. The synchronous belt connects the drive motor and the drive roller, and the annular composite material is mounted on the drive roller and the driven roller. The test fixture also includes a size adjustment device, which is connected to the drive roller and the driven roller. The size adjustment device includes a length adjustment structure and a width adjustment structure, enabling the test fixture to adapt to annular composite materials of different lengths and widths, expanding its application range, and is equipped with parameter adjustment functions.

[0024] The present invention also provides a method for testing based on the above-mentioned testing fixture, comprising the following steps:

[0025] S1) Tooling preparation steps: Install the annular composite material to be tested on the test tooling, adjust the tooling to fit the material specifications through the size adjustment device, and start the running drive device to drive the annular composite material to rotate.

[0026] S2) Condition monitoring steps: The operating status of the annular composite material is monitored by the vibration and warping detection mechanism, and the tooling parameters are automatically adjusted according to the monitoring results until the annular composite material is in the preset working state;

[0027] S3) Synchronous testing steps: Start the intelligent synchronous testing device. The two balance linkage mechanisms independently monitor and adjust both sides of the annular composite material. When the annular composite material is detected to be loose, the corresponding balance linkage mechanism automatically compensates and adjusts through the lever linkage component and the force control component.

[0028] S4) Data acquisition steps: The motion parameters of the two balanced linkage mechanisms are acquired in real time through the synchronous detection structure, and relevant data during the test are recorded;

[0029] S5) Result processing steps: Analyze and process the acquired data to obtain the relevant performance parameters of the ring composite material.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. High-precision dual-sided detection mechanism: Two independent balancing linkage mechanisms are set on both sides of the annular composite material. Each mechanism adopts a lever structure with unequal diameter balancing components, which can amplify the small relaxation changes of the annular composite material into obvious mechanical displacement, realizing the accurate detection of the difference in fatigue strength between the two sides of the annular composite material.

[0032] 2. Linearized Measurement System: The limiting groove of the integrated shaft frame cooperates with the unequal diameter wheel, so that the distance between the unequal diameter wheel and the center of the hinge shaft increases linearly during rotation. This ensures a linear correspondence between torque change and the relaxation degree of the annular composite material, realizes quantitative measurement of the deformation of the annular composite material, and avoids nonlinear errors.

[0033] 3. Intelligent automatic compensation and constant force control: The constant force output device in the force control component can provide a stable and consistent external force. When the loosening of the annular composite material is detected, the position of the movable tensioning roller is automatically adjusted by the unequal diameter balance component driven by the wire rope, so that the annular composite material is restored to the preset tension state, ensuring the continuity of the test process and the repeatability of the data.

[0034] 4. Intelligent synchronous dual-parameter detection technology: The synchronous detection structure connects the horizontal support boxes on both sides through a horizontal frame. Combined with displacement sensors and measuring instruments (level or angle gauge), it can simultaneously obtain two parameters: displacement and angle change, and realize multi-dimensional quantitative analysis of the deformation difference on both sides of the annular composite material.

[0035] 5. High-sensitivity condition monitoring: The vibration and warping detection mechanism uses a brush as a contact sensing element. The brush's flexibility enables it to sensitively detect subtle vibrations and warping changes at the edge of the annular composite material, providing accurate start-stop control signals for the balancing linkage mechanism and enabling condition judgment.

[0036] 6. Stable mechanical transmission: The sliding sleeve at the end of the movable tension roller forms a stable sliding connection with the integrated shaft frame, ensuring smooth movement of the movable tension roller during adjustment, eliminating test errors caused by mechanical shaking, and improving the reliability of test results.

[0037] 7. Optimized geometric layout: The tension roller assembly adopts an inverted isosceles triangle distribution, with the movable tension roller located in the middle and the annular composite material surrounding its lower half-curved surface. This layout maximizes the contact area between the annular composite material and the tension roller, enhancing the deformation transfer effect.

[0038] 8. Wide applicability: The length and width adjustment structures of the size adjustment device enable the testing fixture to be adapted to ring-shaped composite materials of different specifications, including treadmill belts of different thicknesses, industrial conveyor belts of different widths, and conveyor belts of different materials, thus expanding the application range of the equipment and realizing a multi-functional intelligent testing platform.

Detailed Implementation

[0049] Example 1:

[0050] This embodiment provides an intelligent testing fixture for the strength, durability, and bilateral balance of a ring-shaped composite material. It utilizes existing technology to simulate the operation of the ring-shaped composite material for a certain period of time, and detects the durability of the material by testing the degree of deformation and relaxation strength of the ring-shaped composite material. At the same time, through a specific structural design, it obtains and compares the differences in tension strength on both sides of the ring-shaped composite material and the unevenness of fatigue strength decay under the same operating conditions, thereby simultaneously realizing the intelligent detection of the durability and bilateral balance of the ring-shaped composite material.

[0051] refer to Figure 1 , Figure 2 The test fixture includes:

[0052] Test workbench 10 serves as the support and mounting platform for this test fixture. The following devices are all installed on test workbench 10.

[0053] The drive unit 20, employing a double-roller closed-loop drive structure, is used to drive the annular composite material 01 to rotate, simulating actual operating conditions. It includes a drive motor 21, a synchronous belt 22, a drive roller 23, and a driven roller 24. The annular composite material 01 is mounted on the drive roller 23 and the driven roller 24. The synchronous belt 22 connects the output of the drive motor 21 to the drive roller 23. Continuous operation simulates the actual usage state of the annular composite material 01. (This is known technology in the art and will not be described in detail.)

[0054] The size adjustment device 30 is connected to the driving roller 23 and the driven roller 24. It includes a length adjustment structure 31 and a width adjustment structure 32 to accommodate more annular composite materials 01 of different lengths and widths. At the same time, it can adjust the tension of the annular composite materials 01 to ensure that annular composite materials 01 of different material thicknesses and fiber densities can obtain appropriate pretension.

[0055] The tensioning and stabilizing structure 40 is set along the length of the annular composite material 01 to ensure the stable operation of the annular composite material 01, reduce the loosening of the annular composite material 01 caused by vibration, and improve the measurement accuracy.

[0056] The intelligent synchronous testing device 50 is the core innovative part of this testing fixture. (Refer to...) Figure 3 It includes a tensioning roller assembly 51 for transmitting the deformation effect of the annular composite material 01, a two-balance linkage mechanism 52 for converting the deformation of the annular composite material 01 for convenient measurement, and a synchronous detection structure 53 for displaying the detection results.

[0057] The vibration and warping detection mechanism 60 includes two detection frames 61 symmetrically installed on both sides of the annular composite material 01. These frames serve as the basis for judging the operation of the two balanced linkage mechanisms 52. They are used to amplify the vibration amplitude and vibration frequency of the annular composite material 01 at the initial installation stage, so as to facilitate observation of whether the annular composite material 01 is running smoothly and determine the timing for the formal start of testing of the annular composite material 01.

[0058] refer to Figure 3 ,in:

[0059] The tension roller assembly 51 contains multiple tension rollers. In this embodiment, three tension rollers are preferred and arranged in an inverted isosceles triangle shape. These are a movable tension roller 511 located in the middle and fixed tension rollers 512 located on both sides. The annular composite material 01 passes through the three tension rollers in sequence and wraps around the lower half-curved surface of the movable tension roller 511 (see reference). Figure 4 );

[0060] Two balancing linkage mechanisms 52 are respectively set at both ends of the tensioning roller assembly 51. Each balancing linkage mechanism 52 is fixedly connected to the end of the fixed tensioning roller 512 on the corresponding side and movably connected to the end of the movable tensioning roller 511 on the corresponding side. That is, the balancing linkage mechanism 52 is independently adjustable up and down on both sides of the movable tensioning roller 511. After the relaxation strength of the annular composite material 01 decreases (the relaxation strength usually has an uneven characteristic on both sides), the annular composite material 01 can be restored to the expected balance by intelligently adjusting the up and down movement of the movable tensioning roller 511 on one side, so that the annular composite material 01 can be re-tensioned to the set stress level.

[0061] The synchronous detection structure 53 is linked between the two balancing linkage mechanisms 52, and can simultaneously obtain the motion information of the two balancing linkage mechanisms 52 to intelligently calculate the deformation of the annular composite material 01.

[0062] The testing principle of this intelligent synchronous testing device 50 is as follows:

[0063] During operation, the annular composite material 01 may loosen due to material fatigue, resulting in reduced strength and weakened wrapping support from the movable tension roller 511. Since the fatigue levels on both sides of the annular composite material 01 typically differ, the loosening often occurs asymmetrically. At this point, two independent balancing linkage mechanisms 52 can respond to the loosening on their respective sides, using their respective force control components 523 to independently lower the movable tension roller 511 on the corresponding side, re-pressing it against the corresponding position of the annular composite material 01, thus restoring the annular composite material 01 to its tensioned state. The intelligent synchronous detection structure 53 monitors the motion parameters of the two balancing linkage mechanisms 52 in real time, including their displacement, rotation angle, and motion time. Through intelligent comparative analysis of the motion differences between the two mechanisms from the start to the end of the test, it determines the imbalance in the strength decay of the material on both sides of the annular composite material 01, thereby assessing the strength difference between the two edges of the annular composite material 01. Simultaneously, it intelligently compares and analyzes the motion trajectory, response speed, and final position of the two balancing linkage mechanisms 52, quantifying the strength balance symmetry of both sides of the annular composite material 01 under the same operating conditions, ensuring the accuracy and reliability of the test results. To achieve precise compensation adjustment, the intelligent synchronous detection structure 53 is equipped with a calculation control module. By acquiring the displacement values ​​L1 and L2 from the displacement sensors on both sides, it intelligently calculates the displacement difference ΔL=|L1-L2|. When ΔL is greater than the preset threshold ΔL0, the downward movement distance of the movable tensioning roller is calculated according to the compensation adjustment formula ΔH=K×ΔL, where K is a compensation coefficient pre-calibrated based on the material characteristics of the annular composite material 01, usually ranging from 0.8 to 1.2. This calculation method can quickly determine a reasonable compensation adjustment amount, ensuring that the two sides of the annular composite material 01 always maintain a balanced tension.

[0064] Specifically, the balancing linkage mechanism 52 adopts an unequal diameter-lever composite structure, which can be referred to as... Figures 4-6 ,include:

[0065] The integrated shaft bracket 521 is connected to the upper end of the test workbench 10. It serves as an integrated mounting component for other parts in this mechanism and is also fixedly connected to the fixed tension roller 512.

[0066] The lever linkage assembly 522 is the core component of this mechanism, including unequal diameter balancing components 5221 that act as levers. The unequal diameter balancing components 5221 are symmetrically arranged on both sides of the integrated shaft frame 521 (e.g., ...). Figure 4 As shown), including lever arm 5222 and unequal diameter wheel 5223 (as shown). Figure 5 As shown), the upper end of the unequal diameter wheel 5223 abuts against the top plate 5211 of the integrated shaft frame 521, and is offsetly hinged to a hinge shaft 5224 serving as a lever fulcrum. The hinge shaft 5224 is slidably connected within the limiting groove 5225 of the integrated shaft frame 521 (as shown). Figure 5 As shown in the figure), it is also connected to the movable tension roller 511 via a connecting rod (the connecting rod is not shown in the figure), which can be referenced. Figure 5 At the beginning of the test of the annular composite material 01, the hinge shaft 5224 is located at the top of the limiting groove 5225. The end of the unequal diameter wheel 5223 that is shorter than the center of the hinge shaft abuts against the top plate 5211. As the lever arm 5222 rotates downward, the distance between the end of the unequal diameter wheel 5223 that abuts against the top plate 5211 and the center of the hinge shaft 5224 increases linearly.

[0067] Force control component 523 is provided at the lower end of each lever arm 5222, and is used to independently apply a preset external force to the corresponding side unequal diameter balance component 5221, drive the unequal diameter wheel 5223 to rotate, thereby driving the corresponding side movable tension roller 511 to move down, so as to realize force control adjustment.

[0068] In this embodiment, reference Figure 4 The force control component 523 can be implemented by using a steel wire rope 5231, with one end connected to the unequal diameter balance component 5221 and the other end wound around a constant force output device 5232 that can provide a constant external force. The constant force output device 5232 can be a servo winch, a magnetic powder brake, a torque motor, etc. The start of the constant force output device 5232 can be determined by the intelligent control signal transmitted when the corresponding detection frame 61 detects the relaxation of the annular composite material 01, and its stop can be determined by the signal transmitted when the corresponding lever linkage component is in torque balance.

[0069] To ensure the stable movement of the movable tension roller 511 under the drive of the connecting rod, and to prevent wobbling or displacement of the annular composite material 01 during operation due to unstable movement, thus affecting the accuracy of the test, [reference needed]. Figure 4The movable tension roller 511 is fitted with a sliding sleeve 5226 at its end, and the sliding sleeve 5226 is slidably connected to the integrated shaft frame 521.

[0070] The balancing linkage mechanism 52 works in conjunction with the vibration and warping detection mechanism 60 and the synchronous detection structure 53 throughout the entire testing process. The overall testing process is as follows:

[0071] When the annular composite material 01 is initially installed, the size adjustment device 30, synchronous belt 22, tension stabilization structure 40, etc., may not be installed in the optimal position, resulting in large vibration amplitude during the operation of the annular composite material 01. At this time, the vibration and warping detection mechanism 60 can intelligently monitor the smoothness of the operation of the annular composite material 01. If the vibration amplitude is still large, the relevant structures or components are adjusted until the annular composite material 01 reaches a state where testing can begin. Then, the synchronous detection structure 53 is adjusted to make its motion parameters on both sides of the annular composite material 01 consistent or negligible, ensuring the accuracy and reliability of the test results.

[0072] Continuing to utilize the two detection frames 61 of the vibration and warping detection mechanism 60, the two detection frames 61 intelligently monitor the slack on both sides of the annular composite material 01. When one side becomes more slack, the synchronous detection structure 53 immediately starts the calculation program: first, it reads the current values ​​L1 and L2 of the displacement sensors on both sides and calculates the displacement difference ΔL=|L1-L2|; if ΔL is greater than the preset threshold ΔL0 (usually set to 0.5-2.0mm), then the required compensation adjustment amount is calculated according to the formula ΔH=K×ΔL; subsequently, the wrapping support force of the annular composite material 01 on that side to the movable tension roller 511 decreases, and the torque on both sides of the unequal diameter balancer 5221 becomes unbalanced. At the same time, the force control component 523 receives the intelligent control signal from the calculation control module, which causes the constant force output device 5232 to start and wind the steel wire rope 5231, precisely pulling the unequal diameter balancer 5221 to rotate by the corresponding angle, causing the movable tension roller 511 to move down by ΔH distance;

[0073] The annular composite material 01 continues to be tested in a tensioned state, and according to the above steps, the monitoring of the relaxation on both sides of the annular composite material 01 and the subsequent movement of the corresponding active tensioning roller 511 are repeated to tension the annular composite material 01 again.

[0074] When the annular composite material 01 stops running after the test time, the deformation on both sides of the annular composite material 01 can be indirectly measured by measuring the rotation angle of the unequal diameter balance component 5221 or the height difference of a certain position of the wire rope 5231 through the synchronous detection structure 53.

[0075] refer to Figure 2The synchronous detection structure 53 includes a horizontal frame 531, with steel wire ropes 5231 passing through both ends and both mounted on the upper end of a horizontal support box 532 (see reference). Figure 5 The horizontal support box 532 is slidably and fixedly threaded through the steel wire rope 5231, and a displacement sensor (not shown in the figure) is installed inside to monitor the distance between it and the constant force output device 5232. A measuring instrument 533 is installed at the middle position of the upper end of the horizontal frame 531. The measuring instrument 533 can be a level or an angle gauge, etc. When the detection frame 61 detects that the annular composite material 01 test can begin, the horizontal support boxes 532 on both sides and the horizontal frame are adjusted so that the lower ends of the two horizontal support boxes 532 are kept on the same horizontal plane, and the horizontal frame 531 is also kept in a horizontal state.

[0076] At the beginning of the test of the annular composite material 01, the force control components 523 on both sides provide the same preset external force, and the initial values ​​of the displacement sensors and measuring instruments 533 on both sides are recorded. When the annular composite material 01 becomes unbalanced, the corresponding wire rope 5231 pulls the unequal diameter balance component 5221 on that side to rotate, causing the horizontal support boxes 532 on both sides to undergo asynchronous displacement changes. The positions of both ends of the horizontal frame 531 relative to the initial moment also change. At this time, the values ​​of the displacement sensors and measuring instruments 533 on both sides are recorded, and the values ​​are input into the computer system for calculation and analysis.

[0077] The multi-stage test is repeated, one of which involves the test principle process described above (i.e., the overall test process of the balancing linkage mechanism, vibration and warping detection mechanism, and synchronous detection structure). After the first stage of the test is completed and the annular composite material 01 becomes loose and irreversible, the loosened annular composite material 01 can be re-tensioned by the length adjustment structure 31, and the unequal diameter balance component 5221 can be adjusted to return it to its initial state where its shorter end abuts against the top plate 5211. Then, the first stage of the test and analysis calculation is started again to improve the durability of both sides of the annular composite material 01 and the accuracy and reliability of the balance of the two sides of the annular composite material 01.

[0078] refer to Figure 7 The testing frame 61 includes a support 612 and several brushes 613 distributed on the side of the support 612. The edge of the annular composite material 01 is embedded between the brushes 613. The degree of up-and-down shaking and the degree of deformation of the brushes 613 can be observed to determine whether the annular composite material 01 can start testing.

[0079] Meanwhile, the testing frame 61 can also determine the edge warping of the annular composite material 01 after a certain period of operation based on its deformation degree.

[0080] This vibration and warping detection mechanism 60 can also be equipped with a capture camera (not shown in the figure) for high-definition imaging of the deformation degree of the brush, thereby improving the accurate judgment of the operating status and warping of the annular composite material 01 and realizing visual monitoring.

[0081] To ensure the accuracy of the test on the annular composite material 01, it is necessary to ensure that the annular composite material 01 is under tension during installation and remains stable during operation. (Refer to...) Figure 2 The installation structure will now be described in detail.

[0082] The running drive device 20, the active roller 23, and the synchronous testing device 50 are all mounted on the testing workbench 10 via the first mounting plate 11. The driven roller 24 and the testing frame 61 are all mounted on the testing workbench 10 via the second mounting plate 12. Both ends of the active roller 23 and the driven roller 24 can be detachably mounted with end frames 25. The tension roller assembly 51 and the balance linkage mechanism 52 are detachably installed via threaded connection, thereby facilitating the wrapping and installation of the annular composite material 01 on each roller.

[0083] The length adjustment structure 31 adjusts and tensions the annular composite material 01 by moving one end of the driven roller 24. It includes a sliding guide rail 311 set on the test workbench 10, and a second mounting plate 12 is slidably mounted on the sliding guide rail 311. It can be driven by a motor, pneumatic components, or hydraulic components to achieve length adjustment.

[0084] The width adjustment structure 32 includes multiple guide grooves 321, which are slidably connected to one side end frame 25 of the active roller 23, one side end frame 25 of the driven roller 24, and one side balance linkage mechanism 52, respectively, and are fixed by standard parts such as bolts or screws, to adapt to annular composite materials 01 of different widths.

[0085] The tensioning and stabilizing structure 40 includes a connecting plate frame 41 slidably connected to the second mounting plate 12, a driven roller 24 mounted on the connecting plate frame 41, and a stabilizing component 42 abutting against the connecting plate frame 41 along the length direction of the annular composite material 01. The stabilizing component 42 can be implemented by one end of a bolt abutting against the connecting plate frame 41 and the other end threadedly connected to a fixed support block.

[0086] Furthermore, the stabilizing component 42 is provided in two sets. The other set abuts against the drive motor 21 along the length of the annular composite material 01. On the one hand, it can buffer part of the motor vibration and improve the stability of the annular composite material 01 operation. On the other hand, it cooperates with the drive motor 21 to improve the fixed drive after it is slidably connected to the first mounting plate 11. Therefore, the tension of the synchronous belt 22 wrapped between the drive motor 21 and the active roller 23 can be adjusted and kept stable, thereby ensuring the stable power transmission of the drive motor 21 to the annular composite material 01.

[0087] This test fixture is also equipped with a control cabinet 70, which can adjust the parameters of the various electric, hydraulic, or pneumatic components involved in this embodiment.

[0088] Example 2:

[0089] refer to Figure 8 The difference between this embodiment and Embodiment 1 lies in the lever linkage component 522. In this embodiment, the shape of the unequal diameter wheel 5223 is slightly modified, and the limiting groove 5225 is removed (e.g., Figure 8 As shown in the figure, the unequal diameter wheel 5223 can only rotate via the hinge shaft 5224. The protrusion 80 of the unequal diameter wheel 5223 allows it to push the movable tension roller 511 downwards via the sliding sleeve 5226 during rotation. To ensure the movable tension roller 511 returns to its original position during repeated testing, a return spring (not shown in the figure) is connected to the upper end of the sliding sleeve 5226. Therefore, when the external force of the force control component 523 is adjusted to disengage the unequal diameter balancer 5221 from the sliding sleeve 5226, the sliding sleeve 5226 can drive the movable tension roller 511 upwards to its original position via the return spring.

[0090] Compared to Embodiment 1, where the downward movement or return of the movable tension roller 511 is directly controlled by adjusting the stable tension of the wire rope 5231, this embodiment utilizes the protrusion 80 of the unequal diameter wheel 5223 to push the movable tension roller 511 downward, and then uses the elastic force of the return spring to return it to its original position. The design of Embodiment 1 can more accurately control the elastic restoring force of the tested annular composite material 01, achieving more precise intelligent mechanical property testing. Therefore, the lever linkage component 522 of the present invention preferably adopts the structure of Embodiment 1.
