The Application of Support Vector Machine to Structure Damage Identification Based on Vibration Signal

摘要：

The damage identification is the difficult and hot spot in structure domain and is paid close attention by scholars at home and abroad.The support vector machine (SVM),as a new method of statistical theory,is applied to identify structural damage in this paper.The relative change quantity of modal flexibility,used as the characteristic index of damage identification,is input in SVM classifier to identify the location and degree of structural damage.A simulative simply supported beam is set up and input with different level noises.The analysis results indicate that this method is feasible to identify the location and degree of structure damage with low noise.

关键词： damage identification support vector machine modal flexibility.
