摘　　要：为了研究反射面天线在热应力影响下的辐射特性,用Ansys软件对天线进行建模,利用ICEM CFD将形变后的模型导出重新进行网格划分,并通过仿真对比反射面天线理想状态下的自由空间辐射方向图和热应力造成结构形变后的自由空间辐射方向图,分析了天线工作环境温度对天线辐射特性的影响。结果表明,高温环境下反射面天线空间辐射特性有较为明显的降级。In order to study presents the radiation characteristics of the reflector antenna ,the model of the reflector antenna was achieved by Ansys and the model of the reflector antenna changed by the thermal stress was achieved by ICEM CFD. By comparing the antenna pattern between the reflector antenna before the impact and after, there is a way to estimate the effect of the ambient temperature for the radiation characteristic of reflector antenna. Draw the conclusion that the radiation characteristics of reflector antenna are obviously influenced by the thermal stress.
