小波变换进行变速箱故障诊断 首先将s1和s2信号时域谱（s1代表维修前的振动信号，s2代表维修后的振动信号），画出来进行对比，会发现s1信号的振动幅值会比较高；然后对s1和s2分别进行小波分解并画出各层的时域谱，只对比s1和s2分后的最高时域谱，s2更加的具有周期性，且幅值较小，s2周期性不够明显，且振动过于密集。分析完时域谱后开始分析频谱，首先对原信号s1和s2fft转换，得到频谱图，如图，然后再对小波分析后高频部分进行fft转换，做出频谱图。对比后我们发现，在f 2375HZ出（也就是齿轮的啮合频率），s1信号频谱幅值会有急剧的升高，然后，其谐波的幅值也会增大。所以可以推断出该维修前的增速箱的齿轮可能出现问题。(Gearbox fault diagnosis based on wavelet transform s1 and s2 first time domain signal spectrum (s1 behalf of the vibration signal before maintenance, vibration signal s2 representative of repaired), drawn comparison, you will find a signal s1 vibration amplitude will be higher then s1 and s2 respectively wavelet decomposition and draw the layers of time-domain spectrum to only a maximum time domain spectroscopy s1 and s2 points after, s2 is more cyclical and smaller magnitude, s2 cyclical enough obviously, and the vibration is too dense. End domain spectral analysis after the beginning of the spectrum analysis, the first of the original signal s1 and s2fft conversion to give the spectrum, as shown, and then after the high frequency part of wavelet analysis fft transformation to make spectrum. We found that after the comparison, at f 2375HZ out (i.e. the gear mesh frequency), there will be a sharp increase in the amplitude spectrum of the signal s1, and then, the amplitude of the ha)

分支截断算法计算速度快，利用相位质量信息来指导分支设置，可以使分 支尽量设置在质量低的区域，让误差局限在最小范围内，从而获得高质量的解包裹相位。( U5206 u652F u652F u651 u651 u6B09 u6B09 u5B2 U8BBE u7F0E uFF0C u53EF u4E5 u4F7F u5206 u652F u5C3D u91CF u8BBE u7F6E u5728 u8D28 u91CF u4F4E u7684 u533A u57DF uFF0C u8BA9 u8BEF u5DEE u5C40 u9650 U5728 u6700 u5C0F u8303 u56F4 u5181 u5185 uFF0C u4ECE u800C u83B7 u5F97 u9AD8 u8D28 u91CF u7684 u89E3 u5305 u88F9 u76F8 u4F4D u3002)
