【Abstract】 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.更多还原
