摘　　要：在对电动机轴承状态监测与故障诊断的研究中，采用振动诊断技术，即冲击脉冲法编写了电动机故障诊断系统．该系统专门用于电动机轴承的故障诊断与监测，并通过检测冲击点处的冲击波幅值来判断轴承内滚动体与滚道间的碰撞程度，从而有效识别出轴承的工作状态与故障类型，特别适用于检测轴承早期损伤类故障、润滑状况以及油膜厚度等．The motor fault diagnosis system is designed by vibration diagnosis technique, that is, shockimpulse method is especially ed in motor bearing fault diagnosis and monitoring. In this system, the llision degree between roller and roller race has been judged by detecting shocking wave value of shocking point so the bearing status and fault types are recognised. This especially adapts to detect early breakout fault, lubrication status and oil thickness of bearing, etc.
