本文围绕首部结构，根据已有文献资料，开展冰载荷作用下首部抗冰结构耐撞性能的相关研究。利用Ansys软件建立船首和冰体材料的模型，并对软件中各材料数值和单元的选用进行了讨论。通过LS-DYNA软件建立船首撞击冰排的有限元模型，考虑船与冰排的撞击位置和撞击速度等因素，对比研究各种工况下船体结构的损伤变形、能量转化和碰撞力等方面的动态响应，并最终得到上述因素对船首结构造成影响的规律。
The article focuses on the bow structure, and based on the existing literature, carries out the relevant research on the crashworthiness of the bow ice-resistant structure under the action of ice load. The ANSYS software was used to build the bow and ice material model, and the selection of the material values and units in the software was discussed. Establish the finite element model of the ship bow impacting the ice sheet through LS-DYNA software, considering the impact position and speed of the ship and the ice sheet, and compare and study the damage deformation, energy conversion and collision force of the hull structure under various working conditions. The dynamic response of the ship, and finally get the law of the influence of the above factors on the bow structure.
