| 摘 要： | 基于有限元分析方法，对某SUV样车在道路实验过程中后悬架拖曳臂开裂的问题，进行了加速、转向、制动和垂直冲击四种工况分析。结果表明，在制动器支架、制动器支架与拖曳臂本体的焊缝处，出现应力大于强度极限现象，导致了后悬架拖曳臂的开裂。

| Abstract: | Static strength of the trailer arm of a rear suspension system was analyzed using finite element analysis in four cases including acceleration, braking, turnaround and bumper. The analysis showed that there were some regions with highly-concentrated stress on the brake bracket, welds between the brake bracket and the main part of the trailer arm, which resulted in the fracture of the trailer arm. |
