对振动信号进行的EMD分解程序，学习振动的同学可以-Of the vibration signal of EMD decomposition process, students can learn a good look at the vibration

对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。-After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characte

EMD工具箱，用于处理振动信号的一种分解方法，是一种基本的处理振动信号的方法。(The EMD toolbox, a decomposition method for handling vibration signals, is a basic method of processing vibration signals)

利用emd分解轴承振动信号，并通过改进阈值函数来筛选IMF分量，最后对分量做包络分析，诊断出故障类型。(Using emd to decompose the bearing vibration signal, the IMF component was selected by improving the threshold function, and finally the component was enveloped and analyzed to diagnose the fault ty
