基于有限元技术的轿车副车架耐久性设计

对轿车底盘的副车架应用MSC有限元分析软件,进行了耐久性疲劳分析,得到了副车架的应力分布及疲劳计算结果。通过分析和试验,能对副车架的结构优化提供基础,进而提高仿真计算在副车架设计过程中的指导作用。

This paper conducts durability fatigue analysis on the sub-frame, a typical part of car chassis, using MSC finite element analysis software, obtaining the stress distribution and fatigue calculation of the sub-frame. Through analysis and experiment, it will provide basis for the structure optimum of the sub-frame, the guidance of simulation calculation will be boosted in the design of sub-frame.
