Research on Plate Damage Detection by Two-Dimensional Wavelet Analysis

摘要

Wavelet analysis has the characteristics of timing and frequency adapting to each other. Two-dimensional wavelet analysis can rotate and amplify the signal in frequency domain. So, in this paper, two-dimensional wavelet analysis is used to detect the position of the injury of simply supported plate. This article simulates an injury and two injuries in a simply supported plate and the detection of the location of the injury. This article verifies that the feasibility of this method.
