某雷达天线骨架仿真与测试分析

天线骨架是雷达接收、发射、天馈分系统的基础部件，为整个天线系统的主承力结构。风载荷是天线骨架需要承受的主要外负载。文中采用有限元方法对天线骨架在自重和风载荷组合作用下的刚强度进行了仿真分析，然后考虑风载荷的作用对天线骨架进行了实际力学试验，并对仿真设计计算进行了验证分析。结果表明：有限元分析结果能基本反映结构的整体应力水平和变形趋势，该分析方法能够很好地用于天线骨架的设计。试验中对风载的模拟加载方法，可供天线骨架的风载试验参考。

Simulation and Test Analysis of a Radar Antenna Framework

The antenna framework is a basic component and the main bearing structure of the whole antenna system. The wind force is the main external load of the antenna framework. In this paper simulation analysis for the rigidity and firmness of the antenna framework under gravity load and wind force is carried out by finite element method. Then the actual mechanical test is made considering the effect of the wind force and the calculated result is verified. The results show that the finite element analysis results can reflect the stress level and deformation trend of the structure and this analysis method can be used in the design of the antenna framework. This simulation method of wind load in the test can provide useful reference for the wind load test of the antenna framework.
