Elastomer performance testing equipment and elastomer performance testing method

Abstract

The invention discloses elastomer performance testing equipment. The testing equipment is characterized by comprising an upper computer with an assessment parameter, a preloading control parameter anda testing control parameter, a master control module, a servo driving module, a servo electric cylinder, a testing tool and a collection module; and the testing tool comprises a testing table for placing a to-be-tested elastomer, and a testing execution mechanism movably arranged on the testing table and used for applying pressure on the to-be-tested elastomer. The invention further discloses a testing method using the testing equipment. The testing equipment has the advantages that the servo electric cylinder is used for driving the testing execution mechanism to test the to-be-tested elastomer, the equipment space is greatly reduced, the servo electric cylinder can greatly reduce the purchase cost, the equipment maintenance difficulty is reduced, and the control technology of the servoelectric cylinder is comparatively mature, thereby facilitating the user to perform technical support and upgrade; and the whole process is divided into a preloading process and a testing process, theinfluence on the testing by the stress of the to-be-tested elastomer can be effectively eliminated through preloading, and the testing result precision is improved.

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.
