冰撞载荷作用下船舶夹芯抗冲击舷侧结构设计

伴随着"冰上丝绸之路"口号的提出,也为开发北极航道带来了空前的机遇。而北极航区有大量的浮冰存在,船舶航行时难免会遇到船与冰碰撞的问题。在查阅相关文献和掌握理论知识的基础上,利用ANSYS/LS-DYNA建立船舶--浮冰碰撞模型,分别对不同船舶夹芯式舷侧结构与普通结构和浮冰碰撞的损伤情况进行数值模拟计算,根据对数据结果的比较分析选取出一种较优的抗冰载荷作用的结构形式。

Design on Sandwich Anti-I MPact Ship Side Structure under Ice Collision Load

In recent years,our country has put forward the slogan of"silk road on ice",which brings unprecedented opportunities for the development of arctic shipping routes.However,there is a large amount of floating ice in the arctic navigation area,and ships will inevitably encounter the problem of ship-ice collision.On the basis of consulting relevant literatures and grasping theoretical knowledge,ANSYS/LS-DYNA was used to establish the ship-ice collision model,and the damage situation of the collision between the sandwich side structure and common structure of different ships and the ice collision was numerically simulated.According to the co MParison with the result of data analysis a better structure was selected.
