摘要
本文讨论了大气边界层风洞中脉动风压相似模拟所遇到的问题。对自然界脉动风压的相关特性作了分析和简化,从理论上阐述了用指数风压取代阵风脉动风压(含平均风压)的可能性。提出用指数风压对结构模型激振的理论,从而把模型试验全部纳入符合相似关系的定量研究。
In this paper, some problems dealt with similar simulation of fluctuating pressure in the atmospheric boundary wind tunnel are under discussion. The correlative features of natural fluctuating wind pressure are analysed and simplified, and the possibility of using exponential wind pressure instead of gust fluctuating wind pressure (including average wind pressure) is theorectically explained. A theory of the structure model excited by exponential wind pressure has been created and hence the model testing could be concluded in quantitative research which is in correspondence with the similarity relations.
