摘　　要：采用有限元方法对某机载雷达的天线座结构刚强度性能进行了评估。考虑载机的实际环境条件,分别对天线座组件进行了模态分析、冲击响应分析和随机振动分析,分析结果表明天线座结构在雷达整机中具有足够的刚度和强度性能。研究结果表明,通过开展实际环境条件下天线座结构的强度可行性研究,可以为天线座结构的改进设计和减重设计提供重要理论依据。The stiffness and strength of antenna pedestal structure in an airborne radar is evaluated by using the finite element method. The mode analysis, shock analysis and random vibration analysis are conducted in view of the actual environment condition respectively. The analytical results show that the antenna pedestal posses the enough stiffness and strength performance. The findings in this paper are of great significance to the improved esign and the weight reducing design of the antenna pedestal by studying the strength feasibility.
