天线被广泛应用于通信、雷达导航等领域，天线结构的静力学、动力学特性对天线整体的电/机性能有着极其重要的影响。且抛物面天线的口面面积较大，工作环境较为恶劣，因此风荷载成为影响天线正常运转的最主要荷载。文中用有限元法对雷达天线装置在风荷作用下产生的应力应变，进行了详细的分析介绍，并给出了分析的云纹图，以达到为天线处于优化状态下工作提供科学的分析结论和设计依据。

The antenna is widely applied in domains such as correspondence, radar navigation and so on, and the statics/ dynamics characteristic to the antenna structure has extremely important influence on the antenna electricity/machine performance. Also paraboloid antenna mouth face area is bigger and in a bad work environment, so Wind load becomes the mainest load affect the regular work of antenna. In this paper, the analysis of stress and strain on radar antenna equipment based on wind loads is discussed in detail, using finite element method, and corresponding resultant contours are plotted. And which can provide scientific conclusions and design basis for antenna working in a optimizing state.
