摘　　要：对某新型平台动车组牵引变压器油泵轴承异音进行了原因分析,最终通过对故障轴承的能谱分析,确定故障原因,并提出了新的组装工艺及油泵封闭装配室降尘量监测优化方案。The abnormal noise of the oil pump bearing of the traction transformer of a new platform EMU was analyzed.Finally,the energy spectrum analysis of the faulty bearing was used to determine the cause of the failure,and a new assembly process and an optimization plan for monitoring the dust reduction in the closed assembly room of the oil pump were proposed.
