Abstract：
The use of stress wave reflection method to the nondestructive testing of wood structure, wood structural system dynamic response of the wavelet analysis is to find the parameters reflecting the structural system. The presence of defects will be attenuated or enhanced some elements of the response signal within a certain band, so with the normal security compared with the defects affect the normal safe use of wood structure, dynamic response of energy in certain frequency bands of the wooden structure will be shown significantly different. Therefore, the diagnosis can be achieved by the stress wave reflection method and wavelet analysis for wood structural defects.
