摘　　要：大型船舶上的舵除了上舵承、下舵承外,还设置有尾柱支撑,各国船级社认为悬臂在船体上的艉框底骨应视为弹性支座。为了使双支点舵舵杆在设计载荷作用下有足够的强度,本文采用有限元直接计算方法对其结构强度进行校核。The rudder of a large ship is generally supported by the upper bearing, the neck bearing and the stern frame. The classification societies of the world consider that the shoe piece or the horn should be taken as an elastic support. In order to enable the rudder stock of double-pivot rudder to have enough strength under the design load function, this arti- cle adopts the FEM direct calculation method to check the structural strength.
