In this paper, the dynamic model of the intelligent plate with the pasted piezoelectric material is built. Through the dynamic model, the dynamic response signal is simulated when the damage has slightly changes. The re-sponse signal is decomposed by using wavelet packet analysis and a series of sub signals can be obtained. The energy spectrum can be obtained based on sub signals. By comparing with the full structure energy spectrum, the rate of energy spectrum can be obtained. Through the rate of energy spectrum, the detection of damage degree of the intelligent plate is finally realized.
