【摘要】：船舶碰撞事故大多发生在海上,因此事故后很难做到现场勘查和保留证据。在事故调查中,海事执法部门通常依据双方船员的口供和航海日志进行责任认定,带有主观性,难以保证客观、公正。随着现代仿真技术的发展和计算机运算能力的提高,可以将有限元法应用到船舶碰撞事故调查中,对事故进行定量分析,以达到许多传统分析手段无法达到的研究深度。文章以一个真实的碰撞事故为例,采用有限元法在计算机上对船舶碰撞进行模拟仿真,直观再现了船舶碰撞过程;通过对损伤程度进行计算以及对变形形态进行对比,发现利用有限元的仿真结果与实船的破损变形十分吻合。这为事故分析提供了更加科学、客观的依据,所得结论在二审中被海事法庭采纳。
[Abstract]:Most ship collision accidents occur at sea, so it is difficult to do spot survey and keep evidence after the accident. In the investigation of accidents, the maritime law enforcement department usually determines the responsibility according to the statement of the crew of both sides and the log book, which is subjective and difficult to guarantee the objectivity and impartiality. With the development of modern simulation technology and the improvement of computer computing ability, the finite element method can be applied to ship collision accident investigation and quantitative analysis of the accident, in order to achieve a lot of traditional analysis methods can not reach the depth of research. Taking a real collision accident as an example, the paper uses finite element method to simulate the ship collision on the computer, which directly reproduces the ship collision process, calculates the damage degree and compares the deformation pattern. It is found that the finite element simulation results are in good agreement with the damage and deformation of the ship. This provides a more scientific and objective basis for accident analysis, and the conclusion was adopted by the Maritime Court in the second instance.
