摘要：

Aiming at the problem of high failure rate of traction converter power module for some types of electric locomotive, the vibration test standard of electric locomotive equipment is studied firstly, and then the actual line operation vibration test of Yingshuiqiao, Lanzhou and other locomotive depots is carried out. The vibration characteristics of traction converter power module of HXD1, HXD1B, HXD2 and other types of electric locomotive are obtained. Finally, based on the induction theory of load spectrum, the measured load spectrum of traction converter and its components is obtained. The research results show that the vibration of traction converter power module of HXD1 and HXD1C electric locomotives is divided into low frequency vibration of 30~80Hz and high frequency vibration of 700~1600Hz, and the effective value of acceleration is generally higher than that of other types of electric locomotives, exceeding the standard value of IEC 61373. When HXD1 electric locomotive runs on Yingshuiqiao - Wuwei line, the skewness of power module is close to 0, and the return to zero kurtosis is in the range of 2.39~4.03, which belongs to super Gaussian vibration. There is a significant difference between the measured load spectrum of power module and the load spectrum of IEC 61373 standard function test. Line vibration test and load spectrum induction can provide theoretical basis for vibration characteristic analysis and reliability research of traction converter of electric locomotive.
