Collision is one of the common accidents during the lifetime of deep sea submersibles. Now scholars have paid more and more attention to research on collision strength. The FEM is adopted to simulate the collision between two submersibles in this paper. Based on the research on some key collision indices, plastic energy absorption, collision force and critical collision speed, the approach of assessing collision strength was obtained. Besides, we discuss the motion lag of the submersibles and consider the impact of some collision parameters, such as water pressure, impact position, angle, and radius of indenter. Finally, some significant conclusions were made.
