Abstract

In this paper, the dynamic response of ship-borne membrane radome under the impact of water was investigated.Based on smooth particle hydrodynamics (Smooth particle hydrodynamics SPH), a fluid-structure coupling model was established, to simulate the membrane structure impacted by water, and the dynamics of the shipboard radome membrane structure under the impact of the breaking wave water body are simulated by the computer numerical simulation method response.The influence of the initial velocity of water, 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 experimental analysis, under the same impact, the film structure with greater pretension has stronger resistance to impact, that is to say, under the same impact of water body, the greater the pretension of the membrane structure, the smaller the maximum internal stress change amplitude when it is impacted. Therefore, a certain optimal prestress is found to make the entire radome membrane structure suffer the same impact. The minimum maximum membrane stress is generated at the time, so as to achieve the purpose of protecting the fabric membrane structure from large stress and deformation; at the same impact speed, the vertical impact angle has the greatest impact on the membrane structure; under the same impact and pretension, the saddle-shaped film surface has stronger resistance to impact than the flat film surface.
