摘要

摘要: 针对商用车驾驶室等复杂结构的轻量化设计，建立有限元模型。为避免优化的盲目性，提高设计效率，本文对模型进行灵敏度分析，建立各部件对驾驶室整体性能及总质量的贡献度；并进一步提出用相对灵敏度评价方法选择优化变量，简化变量选择过程。最后，提出3种基于不同优化方向的驾驶室结构设计方案：轻质量方案、高刚度方案及综合方案；根据不同优化结果的对比分析，综合优化方案快速实现了总体轻量化设计目标。

Abstract: For lightweight design of complex structures such as the cab of commercial vehicle, the finite element model of the cab is firstly built. In order to avoid blind optimization and improve design efficiency, the sensitivity analysis of the model is carried out to establish the contribution of the components to the cab's overall performance and the total mass. Then the evaluation methods of the relative sensitivity to select optimization variables is proposed, which simplified the process of variable selection. Finally, three structural optimization programs are raised based on different objectives:light quality programs, high stiffness programs and integrated programs; then comparing different optimization results of analysis, the comprehensive optimization program quickly has realized overall lightweight design goals for the cab.
