Disc spring durability test system and method

Abstract

The embodiment of the invention discloses a disc spring durability test system and method. The system comprises a central controller, a relay self-locking circuit, an electromagnetic valve, an air cylinder, a durable rack and a counter, wherein the central controller is connected to the relay self-locking circuit through a one-way switch, the relay self-locking circuit and the electromagnetic valve are sequentially connected with the air cylinder, and the durable rack is used for placing the disc spring. When the system disclosed by the application is used for carrying out a disc spring durability test, the relay self-locking circuit controls the piston of the air cylinder to compress the disc spring back and forth through the electromagnetic valve, when the actual times of compressing thedisc spring reach the preset compression times, the central controller finishes the test, and if the actual times do not reach the compression times, the central controller finishes the test when judging that the deformation amount of the disc spring exceeds the preset allowed threshold value. The disc spring durability test system and method disclosed by the application can monitor the deformation amount of the disc spring in real time, and stop the test when the deformation amount of the disc spring exceeds the allowed range, so that time is saved, and the test efficiency is effectively improved.

Description

technical field [0001] The present application relates to the technical field of spring detection, in particular to a disc spring durability test system and method. Background technique [0002] A disc spring is a disc spring that is tapered in the axial direction and is loaded. Disc spring has the advantages of simple structure, high rigidity and high safety. It is often used as a strong buffer and shock absorbing device and is widely used in heavy machinery, aircraft, automobiles and other industrial fields. Since the disc spring is subjected to repeated alternating stress during use, the disc spring will be damaged or even broken after being used for a certain number of times. In order to ensure the reliability of the disc spring during use, it is necessary to carry out an endurance test on the disc spring before use to test the fatigue life of the disc spring. [0003] At present, most of the durability tests on disc springs use the forward and reverse rotation of the ...
