数据文件的分析与应用，齿轮箱的数据，是实测信号的分析域处理-Analysis and Applications, gearbox data data files, is to analyze the measured signal domain processing

齿轮箱故障诊断中振动信号是非线性、非平稳的，所以在分析振动信号之前需要对信号进行平稳化处理，该段是EMD分解的程序。-Gearbox Fault Diagnosis vibration signal is nonlinear, non-stationary, so before analyzing vibration signals the need for a smooth signal processing, the segment

机械故障诊断方法概述 信号处理方法概述 齿轮箱故障诊断-Mechanical fault diagnosis method outlined signal processing method outlined gearbox fault diagnosis

齿轮箱信号分析处理，去噪处理，小波分析，功率谱分析(Gearbox signal analysis and processing, denoising, wavelet analysis, power spectrum analysis)
