摘　　要：建立某全承载式客车车身骨架有限元模型,在保证车身强度和刚度条件下,提出轻量化设计方案,达到了车身骨架减轻重量的目标。The FEM model of some produced entire-bearing coach body frame has been established. In the case of stiffness and stated strength ,the author proposed lightweight program in order to achieve the objectives of the body frame to reduce weight.

关 键 词：客车车身 有限元法 刚度与强度分析 轻量化研究
