摘　　要：在磁浮车辆设计的过程中,其结构设计是安全运营的基本保障。在CAE(计算机辅助工程)技术迅速发展的时代,通过有限元软件进行相关的分析与计算,无疑是进行磁浮车辆车体结构优化设计的一种快速有效的办法。对闭口型材车体进行了有限元建模,并根据真实受力情况设计了强度计算的工况,然后在Ansys软件中对其进行静强度计算,依据计算结果改进了出现过大应力的部位结构,最后验证了优化后的车体结构能够满足强度要求。During the process of maglev carbody design, structure is the basic guarantee for safe operation. With the rapid development of CAE （computer aided engineering） technology, the analysis and calculation of urban rail vehicle by using the finite element software is undoubtedly a fast and efficient way. A finite element carbody model of closed profiles is established, and the calculation condition is designed according to the real stress state. Then, the static strength is calculated in Ansys software, the site structure where excessive stress exists is improved according to the calculated results. Finally, the optimized structure of maglev vehicle is verified to meet the strength requirements.
