摘　　要：以50m天线为例,介绍了利用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力学分析结果,论证了设计方案的可行性;介绍了利用Pro/E软件进行50m天线的三维结构设计过程,探讨了三维造型软件在曲面成型、参数化设计、尺寸校核、概念设计、辅助安装等方面的应用;阐述了三维造型CAD/CAE技术将在天线结构设计中发挥越来越重要的作用。Based on 50 m diameter antenna, the paper introduces a digitized model using MSC.Patran/Nastran finite element method simu- lation software. The calculating method for load is presented, and the design feasibility is discussed according to the simulation result. The 3D structure design process is introduced by using Pro/e software and 3D model software＇s application is studied in curved shaping, parametric design, conception design, dimension verifying and installing. FinaUy, it is deduced that 3D model CAD/CAE software will play more important role in antenna structure design.
