摘 要：运用HyperMesh软件对某型客车骨架进行有限元强度分析和结构优化。结构优化时，首先确定具体改进区域，再研究不同的后桥段结构方案对整车骨架强度的影响，最后确定一种最优结构，既能保证客车骨架的强度，又能满足实际功能性需求。

Abstract: The authors use HyperMesh software to do the strength analysis and structure optimization for a coach framework with the finite element method. In the structure optimization, they first determine the specific improvement area, then research the influence of different structure schemes of rear axle segment on the coach framework strength,and finally determine an optimal structure, which can not only ensure the coach framework strength, but also meet the function requirements.
Key words: coach underframe; finite element; rear axle segment; strength analysis; structure optimization
