The Application of Theory of Acceleration Power Spectral Density for Structure Damage Detection

JIA Yu-zhuo,LI Yue-bing,XING Shuang,XIAN Peng (Architecture Engineering College of Northeast Dianli University,Jilin,Jilin,132012)  
The damage of the constructor can change its vibration parameter.So,it is a way to detect the damage in the constructor by the change of vibration parameter.Based on the theory of power spectral density (PSD),to imitate the damage by taken away the bolt which connects the beam and to vibrate the beam with actuator,we have achieved detecting the damage by total change of PSD.
