摘要:
针对某型电力机车司机室异常噪声现象,对相关部件进行了振动和噪声测试,研究引起异常噪声的机理。从轮对振动特征、车体振动传递性能、司机室结构模态以及空腔模态等方面开展了探讨和分析,总结和归纳了异常噪声产生的可能原因,确定了轮对多边形失圆产生的低频振动是司机室振动过大的主要原因,司机室板件振动频率与空腔模态的声固耦合振动是诱发电力机车异常噪声的根本原因。
Abstract:
Aiming at the phenomenon of abnormal noise about a type of electric locomotive cab, the vibration and noise of related parts were tested. The wheel vibration characteristics, carbody vibration transmission performance, cab structure mode and cavity mode were analyzed, and the possible causes of abnormal noise were obtained, which was pointed out that the low-frequency vibration caused by polygonal misalignment was the main causes for the excessive vibration of cab, the sound and solid coupling vibration between the vibration frequency of the cab panel and cavity mode was the fundamental cause of the abnormal noise of electric locomotive.
