基于阶次分析的声发射信号归一化方法研究
摘要
Abstract
Because the acoustic emission(AE)signal could be affected by the speed,it could not directly compare different AE signals which are collected under different rotation speed.Therefore,a normalization method for AE signal,which is based on the order analysis,is proposed.In order to removing the affection of speed,the AE signals,which are collected under different rotation speed,should be mapped to order domain based on the uniform angle resampling.The effectiveness of the method is proven by using AE signals which are collected from mechanical seal.关键词
