船舶在冰区环境中航行时，螺旋桨不可避免地会与冰块发生碰撞作用。针对冰区环境冰桨碰撞问题，以显式动力学理论为基础，某多功能船舶的螺旋桨为研究对象，建立了冰桨碰撞模型。使用Ansys有限元计算方法分析了不同速度、不同碰撞位置、不同尺寸大小的冰块对螺旋桨碰撞的动态影响。结果表明，冰块速度、碰撞位置、冰块尺寸对螺旋桨的损坏有着明显影响，定性得出冰桨之间的碰撞规律。
When the ship is sailing in an ice environment, the propeller inevitably collides with the ice. Aiming at the ice and propeller collision problem in ice area, basing on the explicit dynamics theory, the propeller of a multi-purpose ship is the research object, and the ice and propeller collision model is established. The Ansys finite element calculation method is used to analyze the dynamic effects of different speeds, different collision position, different sizes of ice on the propeller collision. The results show that the ice mass velocity, collision location and ice size have a significant impact on the damage of the propeller., and the collision regular pattern between the ice and propeller is qualitatively obtained.
