Dynamic Response of Membrane Structure Under Wind Load

Abstract

In this paper, the dynamic response of ship-borne membrane radome under the impact of wind was investigated. Based on Computational Fluid Dynamics (Computational Fluid Dynamics), a fluid-structure coupling model was established, to simulate the membrane structure impacted by wind, The influence of the initial velocity of wind, the angle of incidence, the initial pretension of the membrane structure and the tensile shape of the membrane surface on the maximum impact deformation and maximum impact stress of the membrane surface are analyzed. According to the experimental analysis, under the same prestress, the greater the wind speed in the wind field, the more obvious the deformation of the membrane structure; Under the same impact, the greater the pretension, the stronger the impact resistance of the film structure; Under the same prestress, the greater the wind speed in the wind field, the more obvious the deformation of saddle membrane structure; Under the same impact and pretension, the saddle film surface has stronger impact resistance than the plane film surface.
