摘　　要：基于某双艉鳍船型在设计中出现的问题,利用CFD的计算技术,深入剖析了该船在实船试航过程中出现的螺旋桨负荷过重、转速不稳定、左右桨转速差别较大、艉部产生较剧烈振动、航速同要求值相差甚远等现象的成因。在实船已经建成,船体线型及螺旋桨均无法改动的情况下,通过切割螺旋桨直径及修削随边、设计并加装整流鳍、采用舵球节能装置等三项综合措施后,成功解决了上述诸多问题,取得了极其显著的效果,得以顺利交船,避免了难以估量的重大损失。Based on the problems in the design of a twin-skeg ship, the paper analyzes the causes of problems during sea trials by computational fluid dynamic method（CFD）. The paper deeply discusses the cause of the problems including propeller overload, unsteady revolution, the great difference between the two propeller revolutions, serious vibration at stern and the ship speed far below the required value. As the ship has been built, the hull form and the propeller cannot be changed. By splitting the diameter and trailing edge of the propeller, designing and fixing contra fin, and installing the rudder ball, the above problems have been successfully solved and gained great effect. At last, the ship is successfully delivered and the immeasurable loss is avoided.
