摘　　要：为探讨极地冰区船舶通过加装船艏冰刀的方式能否改善船冰碰撞结构动力响应的问题,采用非线性有限元方法,从能量转换、应力、应变云图、碰撞力和船速随时间变化关系等多个角度,比较有、无艏部冰刀两种情况下,船舶艏部与排冰发生碰撞时的动力响应规律。结果表明,加装艏部冰刀可减小船体自身的损伤和变形,改善船舶破冰性能。In order to investigate whether the dynamic response of ships in polar ice region under ship-ice collision can be improved by installing bow ice knife,the nonlinear finite element method was used to comparatively analyze the dynamic responses of ship with and without bow ice knife under ship-ice collision,from the aspects of energy conversion,stress distribution,strain distribution,collision force and ship speed varying with time.The numerical results showed that the installation of bow ice knife can reduce the damage and deformation of the bow structure.so as to improve the ice breaking performance of ships.
