船舶电力推进系统螺旋桨负载特性动态仿真

Dynamic Simulation of Propeller Load Characteristics in Ship Electric Propulsion System

采用Chebyshev多项式拟合四象限螺旋桨的特性图谱,依照船舶以及螺旋桨的运动特性搭建船桨的数学模型,分析船舶航行过程中的动态响应曲线,进而为船舶实际中的起航以及停车等操作提供科学、合理的依据。

The Chebyshev polynomial is used to fit the characteristic map of the four-quadrant propeller,according to the ship and the propeller's movement characteristics to build the mathematical model of the paddle.The dynamic response curve of the shipsailing process is analyzed. For the actual operation of the ship and parking and other operations a scientific and reasonable basis is provided.
