摘　　要：简单介绍了车载的可升降50米天线塔架。运用拟静力法计算该塔架的风荷载,利用ANSYS工程软件建立了该塔架的三维空间有限元模型,分析了静力风荷载作用下结构的位移和部分构件的应力。分析结果为该塔架的结构设计提供参考依据,并对该种结构提出了改进意见。This paper introduced in brief the statics simulation of one mobile extension antenna tower with a height of 50m. When developing the analysis model. Wind load forced on the antenna tower was computed with pseudo-static method, and the tower＇s three-dimension FEA model was constructed using ANSYS CAE software. At last, It was obtained the displacement of structure and the internal stress of some key components, under virtual wind load. The simulation results provided reference for structure design of the extension tower, and proposed some improvement advices for this kind structure.
