| 摘 要： | 介绍了小波分析理论和MATLAB小波工具箱,并利用MATLAB小波工具箱进行信号分析。滚动轴承是各种旋转机械中应用最广泛的一种通用机械部件,它的工作状况直接影响机械设备的使用性能。小波分析是一种时频信号分析方法,它具有时域和频域的局部化和可变时频窗的特点,利用小波变换和小波包对信号在不同的频带下进行分解与重构,并对不同的分析方法进行了比较,特别是对不同的小波函数也进行了比较。最后,提出利用数据挖掘的理论来建立轴承故障诊断的数据挖掘模型库。

| Abstract: | Wavelet analysis theory and MATLAB wavelet toolbox are introduced,and using MATLAB wavelet toolbox for signal analysis. Rolling bearing is one of the most widely used component in almost all kinds of rotating machinery.Its working conditions have influence on machinery and equipment performance.Wavelet analysis is a method of time-frequency signal analysis,it has a time domain and frequency domain,their window are variable.Make use of wavelet transform and wavelet packet to decompose and reconstruct singnal... |
