摘要:
为了在线检测自修复添加剂的自修复效果，探讨了小波包能量特征与自修复效果之间的关系，通过试验证明小波包能量特征的方法用于自修复效果评定具有可行性，比频谱分析更直观、准确，同时也为在线检测自修复效果提供一种新的方法。

Abstract:
In order to evaluate the self-repairing effect of the lubricating additives online, the relationship between wavelet packet energy character and self-repairing effect was discussed. It was proved by experiment that the method of wavelet packet energy character for determining the self-repairing effect online is feasible. This method is more directly observable and accurate, comparing with the spectrum analysis, At the same time, It is also a new method for evaluating the self-repairing effect of the lubricating additive online
Key words:  vibration signal  self-repairing  wavelet packet energy character
