Impact Study on Wind-induced Response and Stability for Super Large Cooling Tower with Different Aerodynamic Measures
摘要
Abstract
To study the wind-induced strength and stability properties of large cooling towers with different aero-dynamic measures,the pressures of the rigid-body models without or with three different aerodynamic measures were measured by the wind tunnel tests.A nuclear super-large cooling tower inland was considered as the test specimen. The surface wind mean and fluctuating pressure characteristics were investigated from the test results.Furthermore, finite element analysis was conducted to evaluate the dynamic characteristics of natural vibration,the wind-induced re-sponse,and the overall and local stability.Finally,the effective rules of the different aerodynamic measures on wind resistance for super-large cooling tower were proposed.关键词
