二重动态子结构方法及其在海洋工程结构分析中的应用

THE DOUBLE DYNAMIC SUBSTRUCTURAL METHOD AND ITS APLICATION IN THE STRUCTURAL ANALYSIS OF OCEAN ENGINEERING

根据分枝模态法的概念,对Craig等提出的固定界面法进行了改进,提出一种二重动态子结构法。这样就解决了固定界面法中对接坐标不易减缩的弊病。因而本方法对于节省计算机内存和计算时间有显著效果。

Based on the concept of branch method, this paper describes the improvement of the fixed-interface method advanced by Craig, and suggests a new method—double fixed interface method. This. method can avoid the disadvantage of the fixed-interface method in which the interface coordinates cannot be easily reduced, and can save storage space and computation time.
