考虑流固耦合作用的塔式钢烟囱风致动力响应

Numerical simulation of fluid-structure interaction for wind-induced dynamic response of tower steel chimney

流体-结构耦合作用的力学问题是当前计算风工程领域的研究重点,采用ADINA有限元软件对塔架式钢结构烟囱进行了流体-结构耦合数值模拟计算,得出了该类结构的风振系数和风压分布系数,可供工程参考使用。

Fluid-structure interaction(FSI)problem is the key point in the research on computation wind engineering(CWE).Tower steel chimney structures with fluid-structure interaction(FSI)are introduced and solved using ADINA to investigate the wind-induced dynamic response in this paper.The wind-in¬duced dynamic coefficient and pressure(shape)coefficient which are significant for engineering are calculated.
