Analysis Of Ships Collision With Floating Ice In The Passage Of Arctic

In recent years, the arctic waterway has brought great opportunities to international maritime industry. Meanwhile, it also brings some risks and challenges. Ships sailing in the arctic waterway always encounter the problem of collision with the ice floe. Usually, the consequence of ship collision is very large. Based on the safety of ship collision, this paper studies the main factors of ships and ice collision. In this paper, we study the collision between the163000tons of crude oil vessels and ice floe, using the general finite element software ANSYS to establish finite element model and explicit dynamic simulation analysis software LS-DYNA to simulate the collision process. The different velocity, the thickness of ice, the collision angle and the coefficient of friction factors are considered in the collision process. The main contents of this paper include the following aspects.Firstly, this paper briefly introduces the background and significance of this research, besides, the domestic and foreign research status about ship collisions with ice is discussed.Secondly, this paper introduces the basic knowledge of finite element theory of the collision of ship and ice, and the theory of finite element method about the collision between ship and ice floe.Thirdly, the theory of collision between ships and floating ice is briefly introduced, ANSYS software is used to establish an analytical model, and LS-DYNA simulation software is used in simulation. At last, we get the results of collision force, structural deformation and structural energy absorption.Finally, the results of this paper is analyzed and summarized, the deficiencies and future work is prospected in the end of this paper.
