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.
