摘　　要：针对GK型机车振动大的故障,以检测司机室各频率振动功率能量为参考,分析找出了出现某些振动功率异常的频率,并对机车其他各旋转运动部件进行振动检测,找出了与司机室某些振动功率异常相吻合的频率,进而确诊故障部件。To Solve the problems of vibration with GK locomotive,the vibration energy at all frequances in the driver's cab was tested and analyzed.The frequances at which the vibration energy is higher than normal one were found out.Then,through comparison,the running part whose frequacy coincides with above-mentioned frequancy could be found,and it may be the fault part.

关 键 词：GK型机车 振动 频率 功率
