摘　　要：研究了某型号雷达天线结构有限元分析的基本原理与实现方法，在大型通用有限元分析软件ANSYS中建立25m天线座结构的有限元分析模型，获取天线在不同的工况下应力和应变值以及支座反力。结果表明：在天线设计中运用有限元分析方法可以校核结构技术指标并减轻质量，对局部进行改进消除应力集中，实现结构优化满足天线座的整体强度刚度要求。The basic principle and implemented method of the finite element analysis for radar antenna structure are studied. The finite element model of 25 m antenna pedestal in large general purpose FEM software ANSYS is established to obtain the pedestal parameter in stress and strain under the different working conditions. The results indicate that index checking, weight reduction and regional stress concentration eliminating can be achieved and the structure optimization can satisfy the requirement of strength and stiffness of antenna pedestal.
