摘要
针对某重型载货汽车复合空气悬架导向臂支架在道路试验中失效的问题,建立该导向臂支架的有限元模型,应用有限元法对其进行静强度和疲劳寿命分析。基于连续体结构拓扑优化技术对支架进行优化设计,并对改进后的模型进行静强度、疲劳寿命的计算。结果表明,经过优化设计的导向臂支架强度和疲劳寿命都得到提高,质量也有所减轻,且经实车试验验证了优化方案的可靠性。
To eliminate failure of the support of compound air suspension guide arm of a heavy truck in road test, we construct a finite element model for support of the guide arm, and use FE method for static strength and fatigue life analysis. Optimization design on the support based on the continuum structure topology optimization technology is conducted, and strength and fatigue life analysis are taken on the optimized model. The results demonstrate that the support of optimized guide arm which is improved both in strength and fatigue life features lightweight, vehicle test proves reliability of the optimization scheme.
