基于双向流固耦合的多跨过桥水管模态分析
Study on multi-span fluid conveying pipe with bidirectional FSI method
摘要
Abstract
Chooses a multi -span fluid conveying pipe, utilizing bidirectional FSI method to analyses its dynamic characteristics. Then comparing the bidirectional FSI method with direct FSI method, and unidirectional FSI method. What' s more, this paper considers different velocity. Research results indicate that the bidirectional FSI method can get a more reasonable result; when velocity changes in small range, velocity makes very little difference.关键词
