Research on Reliability Life of Solenoid Valve Based on Life Characteristic Parameter Research
This paper presents an application reliability evaluation method for high-speed railway solenoid valve based on the influence of life characteristic parameters.By simulating and reproducing the service environment of the solenoid valve,the accelerated stress test is designed to shorten the test period.Finally,the lifetime characteristic parameter of solenoid valve is determined as the response time.Evaluate the reliability life of solenoid valves with response time,the results show that the reliability of EMU solenoid valve will be reduced in about 13～20 years under working conditions,and the optimization suggestions for repair program and repair system are given.
