摘要
Abstract
The finite element modal analysis is performed for accurate identification of metal structural crack. The accurately identified model for cracked metal structure is established based on finite element method, and also a database of natural frequency for metal structures is established through analysis of natural frequency for structural model. When any crack occurs in the metal structure, its location and size will be quantitatively figured out by four-wire equal height intersection crack identification technology. This method is proved to be effective through numerical simulation, providing basis for crack identification of metal structures.关键词
