摘　　要：对汽车构件结构疲劳分析和寿命预测方法即静态疲劳分析方法和总寿命S-N预测方法进行了介绍。针对某种型号轿车的悬架,应用多体动力学软件ADAMS构建了悬架的虚拟样机,进行了动力学仿真分析。并应用MSC系列有限元分析和疲劳软件对下控制臂进行分析,计算了其应力特性和疲劳寿命。The fatigue analysis of automobile component which is static state fatigue and S - N fatigue forecast method are introduced. The virtual prototype suspension of an automobile is established by using ADAMS, and the dynamic simulation is cartied out. The low control arm is also analyzed by series of MSC and its fatigue analysis software, then the stress characteristics and fatigue life of the low control arm are calculated.

关 键 词：有限元 疲劳分析 S—N疲劳分析
