The subject is completed by associate professor Jing Shuangxi, Jiaozuo Institute of Technology etc. Through the research of wavelet analysis theory, the algorithm of orthogonal wavelet and wavelet packet graph display is deduced, and it is firstly used in mechanical fault diagnosis.The algorithm combined with the fast algorithm of wavelet transform makes the signal Of the decomposition results consistent with the length of the original data, the original algorithm to solve the existing length of the data with the decomposition layer multiples reduce the problem, and the original count
