摘　　要：简要介绍了小波分析和离散小波变换 ;用作者设计的Matlab振动信号分析处理程序Vbanaly sis,对偏心轴每一个测试点不同方向上的振动实验数据进行分离 ,通过小波变换及多分辨分析 ,对低矮颚式破碎机的偏心轴、整机等振动进行了分析 ;同时指出 ,破碎机振动分析对破碎机的故障诊断和实时监控具有非常重要的现实意义。The wavelet analysis and discrete wavelet transformation are introduced briefly.By use of the Matlab program, Vbanalysis for processing and analysis of vibration signal, designed by the author,the vibration signals from every measuring point on eccentric shaft of jaw crusher are decomposed into the signal of X direction and the signal of Y direction.Then,the vibrations of the eccentric shaft and the whole crusher are analyzed by wavelet transformation and Multi-resolution analysis.Finally,the author points out that the analysis of crusher vibration is of great importance to the diagnosis of crusher faults and the real-time surveillance and control of the crusher.
