Abstract
The reasons of some structural failures cannot be defined. In the reliability enhancement test of an airborne product, a simulation method has been proposed to calculate fatigue damage of random vibration power density spectrum of the fault point within frequency domain. The exact failure times can be calculated accurately and the most possible failure mechanism can be analyzed. In Sect. 5 (Analysis and Verification), the correctness of the results of the simulation analysis has been verified and an optimization design of the product structure has been proposed.
