摘　　要：本文给出了按船级社规定的模型计算舵和舵杆中的弯矩和剪力的公式。舵和舵杆被视为阶梯式变断面梁 ,且尾框底骨或挂舵臂处的支点被视为弹性支座。This paper introduces the bending moment and shearing force calculation formula of rudder and rudderstock according to the model required by classification society. The rudder and rudder stock is looked as stepped non prismatic sections beam, and stern bottom frame or rudder horn fulcrum is looked as plastic backing. Four statically indeterminate structure rudders are introduced in detail.
