Problems solved by technology

[0002] To test the performance of the elastic body, it is usually necessary to apply a test action to the elastic body to be tested through the test equipment to obtain the real-time pressure information, real-time displacement information and test time domain information of the elastic body to be tested during the test, and send it to the host computer by the acquisition module. Then the upper computer calculates and processes to obtain the stiffness value and lag angle of the elastic body to be tested, and compares it with the preset evaluation parameters to obtain the performance test result of the elastic body to be tested. The process of the result is relatively mature; however, the existing MTS dynamic tester used for elastomer product testing uses a hydraulic servo valve to control the oil cylinder, and the system structure is relatively complicated and is mostly used for laboratory testing and analysis; such equipment has large hydraulic noise and equipment occupation Due to factors such as large space and high procurement costs, it is difficult to popularize and apply it on the production line on a large scale. Moreover, the MTS dynamic test system is still in an exclusive monopoly in the industry, and there are great limitations in user technical support and procurement costs.

Embodiment 1

[0017]Embodiment 1: A kind of elastic body performance testing equipment, including upper computer 1, main control module 2, servo drive module 3, servo electric cylinder 4, test tooling and acquisition set with evaluation parameters, preload control parameters and test control parameters Module 5, the test fixture includes a test bench (not shown) for placing the elastic body to be tested and a test actuator 6 that is used to apply pressure to the elastic body to be tested. The movement is set on the test bench, and the host computer 1 sends a preload control The parameters and test control parameters are sent to the main control module 2. The main control module 2 analyzes the corresponding preload control instructions according to the preload control parameters and sends them to the servo drive module 3. The servo drive module 3 controls the servo electric cylinder 4 according to the preload control instructions. The output rod synchronously drives the test actuator 6 to app...

Embodiment 2

[0018] Embodiment 2: the rest is the same as Embodiment 1, the difference is that the preloading mode is the pressure loading mode, the preloading movement interval is the preloading pressure interval, the preloading target value is the preloading pressure target value, and the test loading mode is Pressure loading mode, the test movement interval is the test pressure movement interval.

Embodiment 3

[0019] Embodiment three: use the elastomer performance testing method of the elastomer performance testing equipment of embodiment one, comprise the following steps:

[0020] 1): The elastic body to be tested is fixedly placed on the test bench, and the main control module 2 controls the output rod of the servo electric cylinder 4 to run to the set preload starting position at the set preload speed through the servo drive module 3 ;

[0021] 2): The main control module 2 controls the output rod of the servo electric cylinder 4 to drive the test actuator 6 to apply preloading action to the elastic body to be tested in the preloading motion range until the set preloading cycle is reached. After the cycle, the main control module 2 controls the output rod of the servo electric cylinder 4 to drive the test actuator 6 to run at the set preload speed to a position corresponding to the set preload target value, and use this position as the starting point of the test;

[0022] 3): Th...

Abstract

The invention discloses an elastic body performance testing device, which is characterized in that it includes a host computer equipped with evaluation parameters, preload control parameters and test control parameters, a main control module, a servo drive module, a servo electric cylinder, a test tool and an acquisition module, The test fixture includes a test bench for placing the elastic body to be tested and a test actuator for applying pressure to the elastic body to be tested, which is moved and set on the test bench, and also discloses a test method using the test equipment; the advantage is that it adopts a servo motor The cylinder drives the test actuator to test the elastic body to be tested, which greatly reduces the equipment space. The servo electric cylinder can greatly reduce the purchase cost and reduce the difficulty of equipment maintenance. The control technology of the servo electric cylinder is relatively mature, which is convenient for users. Provide technical support and upgrade; the overall process is divided into preloading process and testing process. Preloading can effectively eliminate the influence of the stress of the elastic body to be tested on the test and improve the accuracy of the test results.
