摘　　要：以18m天线为例,介绍了利用MSC.Patran/Nastran有限元分析软件进行数字化建模的过程,给出了天线载荷的计算方法,并根据系统仿真给出的分析结果,论证了设计方案的可行性。介绍了利用Pro/E软件进行3D实体建模,根据其参数式设计概念和全相关性进行结构设计的过程。阐述了CAE软件将在天线结构设计中发挥的重要作用。Based on the 18 m diameter antenna,the paper introduces a digitized model using MSC .Patran/Nastran finite element method simulation software. The calculating method for load is presented, and the design feasibility is discussed according to the simulation result. The 3D object model is introduced by using Pro/E software and antenna structure design process is presented based on parametric design and correlation concept of Pro/E software. Finally, it is deduced that CAE software will play more impotent role in antenna structure design.
