摘要
在极地海域复杂环境下,船舶在长距离航行中一旦与冰山或大冰块发生碰撞,极短时间内会产生巨大的冲击载荷,可能造成非常严重的海上事故等。运用有限元分析法,借助有限元分析软件ANSYS/LSDYNA对相关船舶球鼻艏与冰的碰撞情况进行数值分析,得到船舶球鼻艏结构的能量-时间关系曲线,以及碰撞力-时间关系曲线,并对各种碰撞参数所导致的结果进行定性的分析和讨论,得到不同初速度的船与冰碰撞以及不同吨位的船与冰碰撞对船舶球鼻艏破损情况的影响,对船冰碰撞领域的研究有一定的指导意义。
Concerning on the issues that once collisions happen between the ships and ice- bergs or ice cakes in a complicated environment of the polar maritime space in a long-distance navigation, it will be likely to cause very serious fortuitous accidents under the impact stress in a short time. According to the explicit finite element method, the situation about the colli- sions between bulbous bow and the ice is simulated and analyzed. Energy-time curve and colli- ding force-time curve of ship bulbous bow structure are obtained. The outcomes resulting from various impact parameters are analyzed and discussed. Influence upon the collisions oc- curring the ice and different initial velocity of ships as well as the ships with different tonnages is obtained. It is of certain directive significance for studying the field of ship-ice collision.
