轨道牵引电机导条涨紧方案

转子导条涨紧是保障轨道牵引电机端部稳定性的重要工序。为了识别涨紧方案对导条槽内紧固特性的影响,优化了转子涨紧制造工艺。应用有限元塑性分析方法,得到涨紧时的应力与变形分布,对导条槽内接触状态与接触压力进行了分析,识别出不同涨紧方案下导条侧边受力相关性影响。同时,基于该方案下的工艺验证与仿真分析结果吻合度高,对牵引电机铁心结构设计与应用具有一定指导意义。

Tightening Scheme of Conducting Bar of Rail Traction Motor

The tightening of rotor conducting bar is an important process to ensure the end stability of the rail traction motor. In order to identify the influence of the tensioning scheme on the fastening characteristics in the conducting bar slot, the rotor tensioning manufacturing process is optimized. The finite element plastic analysis method is used to obtain the stress and deformation distribution when the conducting bar is tensioned. The contact state and contact pressure in the conducting bar slot are analyzed, and the correlation influence of the conducting bar side forces under different tensioning schemes is identified. At the same time, the process verification results of this scheme are in good agreement with the simulation analysis results. It has certain guiding significance for the design and application of traction motor core structure.
