摘要：
Based on the acoustic coupling method in ABAQUS software, this paper adopts the equipment and platform integration analysis method on the study of medium floating shock platform. Discusses the impact of platform shape structure on platform shock environment, and proposes the design scheme to increase the transverse shock spectrum of the platform. First, the preliminary design of the shape structure is carried out to analyze its influence on the platform shock spectrum, and find the key factors which determine the influence degree. Then, optimize the structure to increase the shock spectrum of the platform. The calculation shows that the vertical shock spectrum of the platform is not significantly affected by the addition of baffle structure below the external platform, but the transverse shock spectrum will be improved. Due to the influence of shock wave diffraction and resistance, installing the vertical baffle at the bottom of the side can't obviously increase the transverse shock spectral. The streamlined baffle at the bottom can effectively increase the receiving capacity of the platform on the explosive load. And at the same time, it can also reduce the influence of resistance as far as possible, so as to significantly increase the transverse shock spectrum of the platform. © 2019, Editorial Staff of EXPLOSION AND SHOCK WAVES.
