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仿真,通过大包回转台实测振动信号,进行小波二维灰度分析和三维连续小波变换,清楚地看到了振动信号小波变换情况。
Wavelet analysis theory and MATLAB wavelet toolbook are introduced, MATLAB wavelet toolbook to simulate, and ladle turret sliding bearing vibration signal two - dimensional gray image analysis and three - dimensional continuous wavelet transform image analysis. The wavelet transform situation can be clearly seen.
