地铁车辆牵引电机安装螺栓载荷计算方法研究

Research on calculation method of bolt load for traction motor of metro vehicle

针对地铁车辆牵引电机刚性架悬式结构,提出了安装螺栓载荷的3种计算方法,通过实例对比分析了这3种方法的计算结果差异,为准确计算该类结构的螺栓载荷提供了方法指导。

In view of the rigid suspension structure of traction motor in metro vehicles,three methods for calculating mounting bolt load are put forward in this paper.The differences in the calculation results of these three methods are compared and analyzed through examples.This paper provides methodological guidance for accurately calculating the bolt load in such structures.
