摘　　要：为探索C系列螺旋桨图谱在舰船运动仿真中的应用,提升变螺距螺旋桨舰船运动仿真效果,采用傅里叶级数拟合螺旋桨图谱,改进推力和扭矩系数的螺旋桨推力模型,建立变螺距螺旋桨船舶三自由度运动数学模型。对一艘变螺距船舶进行运动仿真。仿真结果表明,C系列螺旋桨拟合图谱与原图谱吻合度良好。仿真结果与实船试验数据进行比对,误差较小。In order to explore the application of C-series propeller map in ship motion simulation and improve the simulation effect for variable pitch propeller ship ships,The Fourier series function was used to fit the map,and the propeller thrust model was established based on improved thrust and torque coefficient.The mathematical model of three-degree-of-freedom motion of ship was established based on improved propeller thrust model,to carry out the motion simulation of a variable pitch propeller ship.The simulation results show that the fitting map matches the original map.When the simulation results are compared with the experimental data from a real ship,the error is small.
