摘要
采用大型有限元分析软件ANSYS对SS9改进型电力机车车体钢结构进行模态分析,描述了该车体在某一频率范围内的振动模态,分析了影响车体结构的主要因素,并就进一步改善车体动态特性提供了参考依据。
The modal of the steel structure of car-body for SS9 modified electric locomotive is analyzedby the large scale finite analysis software ANSYS. The vibration modal of carbody within certain frequencyrange is described. Main factors influencing the carbody structure are analyzed. Reference basis for theimprovement of carbody dynamic performances are put forward.
