Fluid-solid coupling analysis of 65M radio telescope antenna

In this paper, the essentiality of fluid-solid coupling analysis was addressed, meanwhile the basic principles and fluids of fluid-solid coupling analysis were presented. The fluid field of 65m radio telescope antenna was numerically simulated. The drag coefficient and wind pressure distribution under different wind directions were obtained. The simulated results compared with the wind tunnel experiment and the errors between them were analyzed. The solid field was simulated with the fluid field numerical simulation value, and consequently the stress field and displacement field were obtained. The result demonstrates that fluid-solid coupling method is an effective way for the antenna under wind field to develop engineering problem.
