摘要

提出一种将Kriging代理模型和动力指纹方法相结合的大型复杂结构损伤识别两步法。首先建立结构响应与结构损伤参数之间的Kriging代理模型，代替结构原有有限元模型，对结构损伤进行全局识别，确定损伤位置。然后针对损伤结构，通过动力指纹方法，以结构单元模态应变能曲率差为指标，对结构损伤进行局部识别，确定损伤状况。最后，将该两步识别法应用于某导弹发射台模型的损伤识别中，实验结果表明，该方法可应用于工程实际，为大型复杂结构损伤识别提供了一种新思路。

Abstract

A new two-step method for large complex structure damage identification was proposed by combining Kriging surrogate model with the dynamic fingerprints. First, the Kriging surrogate model between the dynamic response and the damage parameters was established, instead of the former finite model, to global locate the damage. Then, taking modal strain energy curvature difference as index, structure damage was partial identified and damage status was confirmed by dynamic fingerprint method. Finally, the two-step identification method was applied in damage identification of missile launch platform model. The results indicate that the method could be practical applied in project, providing a new idea for damage identification of large complex structure.
