A kind of elastomer performance testing equipment and elastomer performance testing method

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.

Description

technical field [0001] The invention relates to a component performance testing device and a testing method, in particular to an elastic body performance testing device and an elastic body performance testing method. Background technique [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 produ...

[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.
