Abstract

Abstract

In order to investigate the impact environment of submarine and its equipment under underwater explosion and increase the vitality of the submarine, the dynamic response of the model under underwater explosion load is calculated by acoustic-structural coupling method. The propagation of shock wave in water is discussed, and the response spectrum of cabin platform under the combined action of shock wave and bubble pulsation is calculated. The platform response of each cabin under different diving depth, explosive impact factor and explosive attack angle is compared, and the influence of various parameters on the impact environment of equipment is analyzed by combining the acceleration curve and response spectrum curve of cabin plate. The simulation results show that the bubble load will aggravate the platform response, especially in the low frequency band. Therefore, through the study of the impact environment of submarine equipment under different conditions, this paper puts forward reasonable suggestions for the installation position and vitality improvement of the equipment.
