摘要
为解决新开发车型外后视镜因为模态不足而导致的抖动问题,提出针对外后视镜模态计算的有限元分析流程,建立外后视镜模态计算有限元模型,并有针对性地对车门安装点附近进行结构优化,达到了模态设计目标。实车测试验证了有限元分析的精度及可行性。
In order to solve the outside rearview mirror vibration problem caused by low mode,a finite element analysis process for outside rearview mirror mode calculation was proposed,and outside rearview mirror mode calculation finite element model was established,targeted to structure optimization near the door mounting point. Finally the mode design goal was met. The real vehicle tests verify the accuracy of the finite element analysis and feasibility.
