破冰船冲撞式破冰结构强度数值仿真方法研究

摘要

Numerical simulation of collision of icebreaker with ice is investigated with FEM method in this paper. Key issues during the simulation are undertaken, such as impact procedure, calculation of ice buoyancy etc. Simulation of an icebreaker during collision with ice is conducted as an illustrative example and structural strength is accessed. In summarize, the method proposed in this paper is of great significance for strength evaluation of icebreakers.%本文基于瞬态动力学分析法对破冰船冲撞式破冰过程进行有限元数值仿真研究.针对该方法中的船冰撞击分析、海冰浮力模拟等一些关键问题进行研究,根据上述方法对某破冰船冲撞式破冰过程进行数值模拟,并对应力计算结果进行校核.总之,本文建立的一套评价破冰船冲撞式破冰过程船体应力方法,对于中国老龄破冰船的强度评估具有重要意义.
