Analysis Of Ships Collision With Ice Based On ANSYS/LS-DYNA

In recent years, every winter, there would be a large area of ice in China’s bohai sea and yellow sea. Ships sail in these area, freezing or trapped is likely to happen.Freezing or trapped will not only affect ship’s maneuverability in ice areas, decrease the efficiency of goods transportation, but they may also put the ships into danger and threaten the safety of the navigators.Sometimes, ships have to have a collision with ice floe to help themselves.Ships collide with ice floe is a nonlinear process for a short period of time which can be influenced by many factors. In this procedure, ships and ice floe can have deformation and fracture. It is very valuable in practice for the navigators to study the interaction between them.This paper studies the collision between the ship and the ice floe, letting the navigators know the change of ship’s maneuverability in a certain degree, reproducing the process of the collision between the ship and the ice floe by the ANSYS/LS-DYNA program,playing a certain reference and promoting effect on the simulator research on ships sail in ice area.This paper has a review of the studies of ship collision with ice floe, testing methods and relevant literature.Then using the method of finite element analysis modeling, computation and simulation by the aid of the finite element analysis software ANSYS/LS-DYNA.This paper makes a series of related solution and simulation by setting different collision conditions including collision speed,collision angle and the thickness of the ice floe, and has a qualitatively analysis and discuss on the various parameters caused by the collision results. The end of this article summarizes the work having done and prospects the future work, makes a final conclusion of the topic, which has a certain reference value.
