随着全球变暖，冰川消融，极区通航不仅为极区能源开采带来了极大便利，同时大大缩短了欧美与亚洲的航线距离。冰区航行中的船舶安全逐渐成为船舶设计建造时需首要考虑的因素。本文根据极地船舶航行特点，结合国内外行业规范对冰区船舶舵系设备的相关要求及载荷计算方法，运用冰/水动力学理论，研究舵系设备在冰带作用下的载荷算法，并运用有限元法对比了冰区与常规海况下舵设备的结构响应差异，可为实际冰区舵系设备的设计提供一定参考。
With the global warming and glaciers melting, polar navigation not only bring great facility to exploitation of energy in artic region, but also greatly reduce the distance between Europe and Asia. The safety of ship that sail in artic region become the most important consideration when design the ship. Based on the characteristics of polar ship, requirement to polar rudder system by regulations and calculation methods of loads, the paper give some research on rudder system under the ice layer with theory of ice/hydrodynamics. Compared with the structure reaction under the normal sea conditions, the reaction of rudder to the collision of ice belt is carried out by FEM method. The conclusion will provide some reference for design of polar rudder system.
