Abstract

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.
