The method for detecting the damage on the plate by using the wavelet transformation is proposed for the first stage to apply the method to the time series vibration data of the large space membrane. The wavelet analysis is applied to the natural vibration mode and transitional response data by FEM, and the deviation of the wavelet coefficients of damaged plate is calculated for detecting the damage. The results indicate that the damage location on the plate is successfully detected by the wavelet coefficients.
