基于有效信息重构的故障旋转机械振动加速度信号积分方法
Useful Information Reconstruction-based Vibration AccelerationSignal Integral Method for Faulty Rotating Machinery
摘要
Abstract
A faulty rotation machinery vibration acceleration signal integration method was pro-posed based on useful information reconstruction.Firstly,ensemble empirical mode decomposition (EEMD)was utilized to decompose the integral signals.Secondly,the values of kurtosis,mean square error and singular value were proposed to be combined into a feature vector,and further used to ex-tract the effective feature for the decomposed signals.Then,the effective feature components were ex-tracted by Euclidean distance search.Finally,the effective feature components were reconstructed by threshold limit,and the desired integral signals were obtained.The effectiveness and practicability of the method were testified by simulation analysis and measured data.Results indicate that this method is excellent at removing noise and reserving effective feature information,and possesses high precision and superiority.关键词
