摘　　要：结合工程实例,采用Midas有限元软件对双曲线型冷却塔进行有限元建模及结构分析,介绍了在Midas中有限元模型建立过程及荷载施加方法,对比了在自重作用、温度作用和风荷载作用三种工况下冷却塔塔筒的位移、应力和内力分布规律。分析结果可为双曲线型冷却塔结构设计提供参考。In combination with the engineering example,the MIDAS finite element software was used for establishment of finite element model and structure analysis of hyperbolic cooling tower,the process and load application method of finite element model in MIDAS was introduced,and the displacement,stress and internal force distribution rules of cooling tower under three working conditions of gravity,temperature load and wind load were compared. The analysis results can provide reference for the design of hyperbolic cooling tower structure.
