摘　　要：利用声发射信号的特点 ,在滑动轴承试验台上模拟故障并进行诊断 ,取得了较好的效果。实验结果表明 ,声发射信号具有对轴承工作状态的变化敏感、响应时间短、抗干扰性能好、及传感器安装方便等优点。Acoustic emission (AE) is used to detect contacting fault of sliding bearings. The contacting fault was simulated on a sliding bearing by gradually reducing the oil supply until no oil being supplied. AE signals were recorded during the simulation for analysis. The results indicate that AE signals are sensitive and quick response to the changes in the working condition of sliding bearings, good in anti disturbance and easy to install, showing a prospect to be applied to fault diagnosis of sliding bearings.
