摘要：

The research aims to establish an analytical method for ship collision considering the deformation of the striking bow and the struck side structures. The nonlinear finite element method was employed to conduct the bow-side collision. The striking bow was modeled as a rigid and deformable body respectively to investigate the influence of bow deformability on the prediction of final cabin damage. The analytical prediction of the integrated side structure under ship collision was achieved by summing up the individual component results and making some corrections. The analytical results were verified with numerical simulations. Based on the resistance-displacement curve of the striking bow and the theoretical method for the struck side structure, the relative strength between the bow and the side structure can be updated during the collision, which formed a new method predicting the deformation of the struck cabin and the striking bow simultaneously. Finite element simulation results were used to verify the prediction results of this method. It shows that the new method can effectively consider the interaction of the bow and cabin, and improve the prediction accuracy of ship collision damage. © 2024 Editorial office of Ship Building of China.
