Research on the Random Vibration Cumulative Fatigue Damage Life Based on the Finite Element Analysis

Abstract:

Aiming at most of the aviation products are facing the problem of fatigue fracture in vibration environment, we analysis the structure of a bracket with ANSYS-Workbench, predict the life of the bracket by different ways, and compared with the testing result, then use the Fatigue damage spectrum (FDS) and Extreme Response Spectrum (ERS) to analysis expected results. The research not only ensure the accuracy of simulation analysis and life predict, but also make a dynamic supervision of product life process, promote the application of finite element simulation analysis in engineering practice.
