Abstract
In order to predict the durability of car front suspension structure,a finite element model was built,the strength with the maximum load of real road spectrum was analyzed and the durability with the dynamical real road spectrun was analyzed.By contrast,the maximum stress value and the position of the vehicle are fully consistent with the experimental result,fatigue analysis also showed severe fatigue damage.The example shows the strength and fatigue analysis with finite element can predict the durability of front suspension structural parts.In the early days no actual load conditions,with correlation road load maximum,the strength analysis can predict the durability.Finally,to optimize front suspension structure design showed that to enhance the material properties was more pronounced than to increase the thickness.There are not obvious improvement by reducing the bushing stiffness.关键词
