摘　　要：近年来,北极海运、极地资源开发等日益受到各国的高度重视。由于极地海域的地形、天气等因素的影响,使极地海域的开拓面临着巨大的挑战。本文对浮冰与船体舷侧碰撞响应进行了分析,采用ANSYS对浮冰和破冰船船体舷侧进行三维建模,模拟破冰船在-20℃的条件下与不同浮冰碰撞时的舷侧应力以及能量等响应特性。通过对冰船碰撞仿真结果的对比分析,得出冰船碰撞响应的规律,即碰撞产生的应力和内部能量随冰块的撞击速度和厚度增加而增加,随舷侧板厚的增加而减小,随浮冰与舷侧中心接触面积的增大而减小。With the Arctic sea transport,the development of polar resources and so on are increasingly valued by all countries.Due to the influence of topography,weather and other factors,the exploration of polar sea is faced with great challenges.In this paper,the collision response between floating ice and hull side is analyzed and studied,and three-dimensional modeling of floating ice and hull side of icebreaker is carried out with ANSYS to simulate the response characteristics such as side stress and energy of icebreaker when it collides with different floating ice at-20℃.Through the comparative analysis of the simulation results of ice ship collision,the law of ice ship collision response is obtained:the stress and internal energy generated by collision increase with the increase of ice impact speed and thickness;It decreases with the increase of the thickness of the side plate.The contact area between the floating ice and the center of the side decreases with the increase of the contact area.
