Abstract: In order to gain an in-depth understanding of the impact of the type of shell on the internal components of a buoy during the water entry process of the marine drifting buoy, three factors, shell material,shell thickness and shell shape, are properly selected in this paper. Based on the orthogonal experimental design,the maximum Mises stress and strain of the buoy center plate are used as indicators, and finite element simulation analysis has been performed using ABAQUS. The results show that the influence of shell factors on the stress and strain of the center plate is basically the same. The shape of the shell has a significant effect on the stress and strain of the center plate. In the experiment, the center plate is spherical in shape and the material is ABS. The ultimate Mises stress and the deformation occurring are minimized when the thickness is 4 mm.
