摘　　要：舰艇在大风浪中航行,当航向已定时如何确定最大允许航速是航海界关注的课题。采用CFD(计算流体力学)方法和耐波性理论相结合的新模式,分别研究了浪增阻、风增阻及螺旋桨推力损失的计算方法,给出了比较精确的舰艇大风浪航行时的船体负载。在此基础上,运用船-机-桨理论,提出了一种最大允许航速(轮转速)的求解方法。For ships navigating in heavy sea, when the direction is settled, how to determine the maximum speed allowed is a subject of much concern in navigation circle. A new model integrating CFD （Computational Fluid Dynamics） method with seakeeping theory is adopted in this paper, the calculation method of wave wind resistance enhancement and propeller＇s thrust force loss are researched respectively, a relatively exact hull load of ship navigating in heavy sea is approached. Based on this, hull-engine- propeller theory is used to solve the problem of calculating the maximum speed （wheel speed） allowed.
