| Abstract: | In this paper,basic theory of wavelet transform and basic principle of wavelet singularity for mechanical fault detection are introduced.A new type of fault detection strategy based on wavelet singularity is presented,and fault detection and positioning is completed by the modulus maxima point distribution in transform.results of simulation verify the effectiveness of the method. |
