摘　　要：根据现行25型硬卧车车体钢结构的特点,利用I-DEAS软件,建立了车体钢结构的力学模型,分析了车体钢结构的强度、刚度以及模态.并根据有限元分析结果,对车体钢结构提出了改进建议.结构改进后,车体钢结构的质量下降了2 400 kg,较好地实现了车体钢结构的轻量化设计,为车辆的设计部门提供参考.According to the characteristics of steel car body structure of 25 hard sleeping car, a mechanics model of the steel car body structure is constructed by utilizing I - DEAS software, and the strength, stiffness and mold of the car body are analyzed. Based on the finite element a- nalysis results an improvement scheme to the steel car body structure is proposed. The weight of the car body is reduced by 2 400 kg after the structure improvement, and the structure optimization of the car body is realized, which provides a reference for the vehicle design.
