摘　　要：在保证某重型货车驾驶室安全性的前提下,进行轻量化设计研究。首先建立驾驶室有限元模型,根据商用车ECER29法规,对驾驶室进行顶压、前压、后压工况的仿真分析,得到驾驶室的应力分布和变形情况。在此基础上,基于上述3种工况进行灵敏度分析,确定可进行优化的驾驶室零件。再对优化后的驾驶室进行仿真分析,并对分析结果进行了试验验证。在减重22kg的同时,整体上提升了驾驶室的安全性,达到了设计目标。通过探索重型货车驾驶室轻量化优化方法,为同类产品结构设计提供了参考。While ensuring the safety of heavy trucks, lightweight design was carried out. According to ECE R 29 regulations, a finite element model （FEM） of the cab was established. FEM simulated pressure on the front, top and rear part of the cab respectivel~ and then the stress distribution and deformation were obtained. On this basis, sensitivity analysis was carried out weight parts were selected to optimize the design for those three working conditions, and the potential light Then optimization results were validated by the tests. The lightweight design reduces 22 kg weight of the cab while improving safety. The lightweight optimization method provides a reference for the design of similar products.
