主　　题：side structure crashworthiness filling sandwich ship collision 

摘      要：Ship collision accidents are catastrophic accidents, and as the main energy-absorbing structure, the anti-collision capacity of the side structure has an important influence on the crashworthiness of the ship. It is necessary to improve the crashworthiness of the ship by increasing energy absorption of the side structure, in such ways as adding a filling sandwich in a single hull. The aim of the present study is to discuss the crashworthiness of the side structure stressed under lateral dynamic loads through simulation with the finite element code MSC/Dytran. The collision force, the damage deformation, the critical collision speed as well as the energy absorption of a side structure improved with a filling sandwich are compared to the standard structure through numerical simulations. The results indicate that a sandwich panel structure is an advanced ship protection structure that can remarkably improve the ability of the side structure to withstand collisions; the effect of the tube-style sandwich panel structure has the best results. The outcome of this study provides a reference for the crashworthiness assessment of side structures and the crashworthiness optimization design of new side structures.
