摘要

In order to identify the crack of the sprocket wheel correctly, the wavelet finite element method is studied in depth. Firstly, the progress of study on the wavelet finite element method is summarized, and then the basic property of wavelet analysis is analyzed, and then the wavelet finite element theory model of sprocket wheel in sintering machine is studied, and the Daubechies wavelet plate element and isoparametric plate element of crack tip are established, and then the theory of constructing crack identification database of the crack for sprocket wheel is studied, and finally the effective of this method is verified by identify the sprocket wheels with five kinds of cracks based on the vibration test, and results showed that this method can identify the crack of the sprocket wheel correctly.
