岳阳洞庭湖大桥模型动力相似理论分析
Dynamical Similarity Theory Analysis to the Model of Yueyang Dongting Lake Bridge
【摘要】 利用相似理论分析了岳阳洞庭湖大桥模型的动力相似准则 ,利用模态分析理论得出各模态参数的相似比 ,进一步探讨了实际模型在近似满足动力相似下的相似关系 ,得到了理想与实际两种条件下各动力参数的相似比值。
【Abstract】 The dynamic similarity principle of the model of Yueyang Dongting Lake Bridge is analyzed by similarity theory, and similarity ratio of modal parameters is got by modal analysis theory. Similarity ratio of dynamic parameters under the conditions of ideal and real are got by further discussing the similarity relation of real model under approximately meeting dynamic similarity.
