Abstract:The failure process of component is studied when random load acts for many times, and the reliability model of component under random load acting for many times is built. From the statistical meaning of random load action, the cumulative distribution function and probability density function of equivalent load are developed according to the property of order statistics when load acts for many times. The reliability model of component with single failure mode is built with the stress-strength interference model. Finally, the simulation experiment is carried out for the reliability medel built with Monte Carlo method, and the result shows that the model built is right.
