首都机场新塔台模型风洞模拟相似理论分析

【摘要】 利用相似理论分析了首都机场新塔台结构气动弹性模型风洞实验的相似准则 ,得到了塔台结构气动弹性模型的相似参数及模型参数的缩尺率。在利用相似理论得出相似比的基础上 ,进一步探讨了实际模型在近似满足相似关系的处理方法更多还原

【Abstract】 The wind induced vibration similarity principle of the model of new tower structure on Beijing airport is analyzed by similarity theory,and similarity ratio of modal parameters is got by model analysis theory.Similarity ratio of wind induced vibration parameters under the conditions of real are got by further discussing the similarity relation of real model under approximately meeting dynamic similarity.更多还原
