轴承外环故障诊断，故障设置为外环局部剥落，故障特征频率为外环通过频率或倍频理论计算得到475.6Hz.(Bearing outer ring fault diagnosis, fault set to the outer ring local spalling, the failure characteristic frequency for the outer ring through the frequency or frequency theoretical calculations 475.6Hz.)

MFCC,即倒谱系数，也是语音的一个特征之一，能够充分利用人耳的特性 ％ 具体的求法就是预处理，然后加窗，进行傅立叶变换，再求出功率普 ％ 然后得出其自然对数，最后进行dct变换 ％ 代码是用matlab写的，用到的一个语音工具箱，可以从网络上下载。(MFCC, that is, just a few pedigree, as well as a voice of one, to take full advantage of people's ears% of the specific characteristics of the solution is pretreatment, then increasing the window, Fourier transform, another sought power pu% then come to its natural logarithm, culminating transform% Extra code is written in Matlab. use of a voice box can be downloaded from the Internet.)
