| 摘 要： | 建立了机车车体结构特征的分析用模型，包括机车活动顶盖参与或不参与承载的2种情况。用不同的单元将结构离散，计算了结构的振动模态。对第一阶模态的振型作了分析比较，并以SSTD电力机车车体为例进行了有无顶盖时的模态计算，说明顶部刚度对车体第一阶模态振型的影响。

| Abstract: | A model is built for analysis of locomotive carbody characteristics, in which the sliding roof cover is considered to be loadedand unloaded. The vibration modes of the structure are calculated by dispersing the structure with different element. The model at the firststep is analyzed and compared. Mode calculations are done to the SS7D electric locomotive with and without the cover, showing the influenceof the roof stiffness on the vibration type under first step mode of the carbody. |
