Design and Verification of Rigidity and Strength Performance of a Reflector Antenna with Cover

文中以某带罩反射面天线为研究对象,设计了模拟复杂环境载荷的曲面天线刚强度性能试验,通过风洞试验验证了设计试验的可行性,为电子装备的安全服役提供保障。文中重点讨论了复杂曲面天线模拟风载的近似加载方式和刚强度性能试验分析方法。最后,对比了模拟风载和风洞试验形变测试结果,发现两种试验方法的最大误差在6%以下,证明了实验室模拟风载校核天线刚强度性能的可行性。同时,试验结果显示该带罩反射面天线刚强度满足设计要求。

Taking a reflector antenna with a cover as the research object and a curved antenna rigidity performance test that simulates complex environmental loads is designed in this paper. The wind tunnel test verifies the feasibility of the design test and provides a guarantee for the safe service of electronic equipment.The approximate loading method of the complex curved antenna simulating wind load and the test analysis method of rigidity and strength performance are mainly discussed. Finally, by comparing the simulated wind load and the wind tunnel test deformation test results, it is found that the maximum error of the two test methods is lower than 6%, which proves the feasibility of the laboratory simulation wind load to check the rigidity performance of the antenna. At the same time, the test results show that the rigidity and strength of the reflector antenna with a cover meet the design requirements.
