基于Kriging代理模型的结构损伤识别新方法
A New Structural Damage Identification Method Based on Kriging Surrogate Model
摘要
Abstract
A new damage identification method was proposed based on Kriging surrogate model. The initial samples were used to construct the initial Kriging surrogate model to represent the relaG tionship between the dynamic response and the structural damage parameters instead of that between the dynamic response and the structural physics parameters.Reducing the finite element mesh generaG tion and the finite element calculation during the damage identification effectively,the efficiency of damage identification was improved.Updating the Kriging surrogate model by sampling criterion, making sure the Kriging surrogate model might exactly describe the relationship between the dynamic response and the structural damage parameters.A numerical example of a tube and grider structure was given to prove the effectiveness of the method.Finally,the method was used in damage identificaG tion of a missile launch platform model.The results show that the method is effective.关键词
