Effect of the fatigue data editing technique associated with finite element analysis on the component fatigue design period

摘要

The present study concerns development of accelerated fatigue design time based finite element analysis (FEA) through a combination of the fatigue data editing (FDE) technique and FEA. Country road, pavement and highway fatigue data histories were collected using a fatigue data acquisition system. The component durability was evaluated using both original and editing fatigue data signals. Both signals showed a large difference in the CPU time. Furthermore, the histories were successfully edited by presenting the predicted amount of the fatigue damage as the original histories. As a consequence of application for automotive lower suspension arm, this technique can be applied in performing a fatigue history editing, especially in compression of data set. Briefly, design time was saved based on FDE technique associated with FEA.
