摘　　要：为探索一套简便快捷用于分析破冰船推进功率与破冰能力匹配性的方法,利用ABS规范对4艘不同等级的破冰船进行最小推进功率计算,并以此为依据开展破冰工况螺旋桨设计。最后考虑船形状、船体参数、螺旋桨推力以及冰的物理性能,基于Цай Л.Г半经验破冰厚度公式估算了4艘破冰船的破冰厚度,对比估算的破冰厚度与实船破冰能力之间的偏差<30%。研究表明,本文探索的推进功率与破冰能力匹配性分析方法实际可行,可为破冰船设计者提供一定参考。In order to explore a simple and fast method for analyzing the matching between propulsion power and ice breaking capacity of icebreaker, the minimum power of four icebreakers of different classes was calculated by ABS code and the propeller design under ice breaking condition was carried out based on the calculation. Finally, considering the bow shape, hull parameters, propeller thrust and the physical properties of ice,the ice breaking thickness of four icebreakers was estimated based on the semi empirical ice breaking thickness formula of Цай Л. Г.The deviation between the calculated ice breaking thickness and the ice breaking capacity of the real ship is less than 15%.The research shows that the matching analysis method of propulsion power and ice breaking capacity explored in this paper is practical and feasible,which can provide some reference for icebreaker designers.
