摘　　要：为避免螺旋桨图谱计算的复杂性,提出一种新的螺旋桨建模方法.该方法基于回归算法计算螺旋桨的推力和转矩,可进行四个象限的仿真.结合船桨系统运动方程,进行船舶起航、停车、倒车等基本工况的仿真.分析各种工况下螺旋桨转速、船舶航速和螺旋桨转矩的变化情况,可为船舶实际操作提供可操作性的建议和理论依据.To avoid the complex calculation with propeller chart, a new modeling method for marine propeller was put forward.According to the new modeling method , propeller thrust and torque were calculated based on regression algo-rithm, and four quadrant simulations were realized .Combi-ning with mathematical model of the ship-propeller , basic ship operations such as start , stop and emergency astern were sim-ulated.The change curves of the revolution speed of the pro-peller, navigation speed of the ship and the torque of the ship under all kinds of working conditions were analyzed , which can give some operable suggestions and theory evidences for the practical operation of the ship .
