摘要
针对T型天线结构几何非线性的特点,分别应用小垂度柔索理论和有限元分析软件ANSYS对其结构进行了找形分析计算.通过对两种方法找形结果的比较,表明基于ANSYS软件对T型天线结构找形是可行的.然后在该结构形状的基础上,又利用ANSYS对该天线结构引下线为固支时的情况进行了风荷静力学响应分析.最后,通过工程实例的计算结果验证了文中的分析模型及计算方法的合理性和有效性,表明利用ANSYS软件能够对线天线结构很好地进行找形分析与风荷静力学响应分析.
According to geometric non-linear characteristics of the T-type antenna structure,the form finding analysis of wire antenna was achieved by small sag flexible cable theory and finite element analysis software ANSYS,respectively.Compared with the results obtained by the two methods,it indicates that form finding analysis of T-type antenna structure was feasible by the ANSYS software.Then based on above-mentioned form,ANSYS software was used for analysis of the antenna with downlead line fixed under wind load.Finally,the rationality and feasibility of the analysis model and computational method were illustrated by engineering project.Results show that form-finding analysis and static response analysis of wire antenna structure under wind load can be carried out by ANSYS software.
