| 摘 要： | 建立某机车车体有无蒙皮结构的2种有限元实体模型；分析了蒙皮结构在车体结构有限元分析中的具体影响；提出了车体蒙皮结构在动态特性计算中的处理方法。指出要提高机车车体结构的有限元分析精度，就必须考虑蒙皮对结构动态性能的影响。

| Abstract: | Two finite element models of a locomotive carbody with or without cover structure are established. The influence of cover structure on car-body is analyzed. The processing method of the carbody cover in the calculation of dynamic performance is proposed. It is pointed out that, to improve the accuracy of finite element analysis of carbody structure, the influences of cover structure on the dynamic performance must be taken into account. |
