Performance Reliability Simulation Analysis for The Complex Mechanical System

Large sample failure data for traditional probability statistics methods usually cannot be obtained from over-sized and complex mechanisms, which makes its reliability prediction very difficult. In this paper, the physics of failure technology is considered for the failure of products thoroughly. With computer simulation, the kinematic performance reliability of an aircraft cabin-door-lock mechanism is researched in this article. The example shows that the method combining physics of failure and software simulation method can solve the reliability problem of complex mechanical products effectively, which will bring guiding significance to engineering practice.
