摘要： 文章针对商用车底盘悬架轻量化开发，利用 HyperWorks 和 FEMFAT 软件对底盘减振 器支架进行结构强度分析和疲劳强度分析。采用结构优化方式完成减振器支架轻量化设计， 优化前后结果对比，在满足静强度和疲劳寿命的前提下，减振器支架减重了 14.83%，成本降 低了 33.96%。通过小批量试制和整车试装验证，证实了有限元分析结果和实际情况的吻合性， 达到了整车轻量化、降成本的目的。

Abstract: Aiming at the lightweight development of commercial vehicle chassis suspension, HyperWorks and FEMFAT software are used to carry out structural strength analysis and fatigue strength analysis on the chassis shock absorber bracket. The structural optimization is adopted to complete the lightweight design of the shock absorber bracket. The results before and after optimization are compared, and the static strength and fatigue life are satisfied. The weight of the shock absorber bracket is reduced by 14.83% and the cost is reduced by 33.96%. The result of finite element analysis is proved to be consistent with the actual situation through small batch trial production and vehicle trial assembly verification, and the purpose of vehicle lightweight and cost reduction is achieved.
