摘　　要：对某款豆浆机进行噪声水平及振动测试。通过对振动信号进行频谱分析、噪声自功率谱和1/3倍频程分析以及噪声与壳体振动相关性分析,找到主要噪声源。基于MATLAB的图形与计算功能,对该机的双层隔振系统进行优化改进,解决了噪声超标问题。Noise and vibration of a soymilk maker had been tested. The main noise sources had been found through analyses of the frequency of the vibration signals, the self-power spectrum and a third octave,and the correlation about the noise and the frame vibration. Then the parameters of the maker＇s double isolation system have been optimal designed based on the graphical and quantitative analysis in MATLAB so that the noise of the maker has been cut to the permissible range.
