摘　　要：本文叙述了将声发射检测技术应用于火车货车滚动轴承故障诊断中,通过小波包分析提取滚动轴承声发射信号的能量特征,并通过小波包消噪处理法突出能量特征,以达到较好故障诊断效果。This paper describes the acoustic emission detection technology used in fault diagnosis of the train truck bearing. Through the wavelet packet analysis the energy characteristics of AE signals of bearing extracted and with denoising by wavelet packet the energy feature is more prominent and is used to achieve better fault diagnosis.
