多重多级子结构方法与模态综合法的对比研究
Comparative Study on Multiple Multi-Level Substructure Method and Modal Synthesis Method
摘要
Abstract
The multi-level substructure method was compared with the traditional dynamic sub-structural modal synthesis method (the super element method for MSC. Nastran). By using Lanczos method and technology of substructure tree travelling, the contribution of the multi-level substructure method's internal freedom of substructure for the whole solution is consid-ered. The result could be improved significantly, and which also had the same calculation accu-racy with the overall structure without condensation. The numerical results show that the multi-level substructure method is more flexible than the traditional modal synthesis method in divid-ing substructure and calling multi-level substructure, which is not limited by the complex sub-structure and more accurate at higher frequencies.关键词
