冰体质量和撞击角度对船首结构碰撞性能的影响

Influence of Ice Mass and Impact Angle on Collision Performance of Bow Structure

以极地航行运输船的艏部结构作为研究对象,采用ANSYS对船首结构和冰体进行建模,结合非线性有限元软件LSDYNA重点研究冰体质量和船冰撞击角度对船首结构的影响,得到冰载荷下船首结构的损伤变形、碰撞力等方面的变化特征。结果表明,冰体质量和撞击角度的改变会给船首结构带来不同程度的损伤变形。研究结果对分析船舶与冰体的碰撞性能具有参考价值。

Taken the bow structure of the polar navigation transport ship as the research object, the ship bow structure and ice body are modeled by ANSYS, and the effects of ice mass and ship ice impact angle on bow structure are studied with LS DYNA.The characteristics of damage, deformation and collision force of bow structure under ice load are obtained. The results show that the change of ice mass and impact angle bring different degrees of damage and deformation to the bow structure. The research results have reference value for analyzing the collision performance between ship and ice body.
