基于Simulink的船舶运动模型动态仿真研究

Dynamic simulation of ship motion model based on Simulink

为进一步研究船舶操纵性能,根据船舶旋回性指数(K)、追随性指数(T),建立船舶运动的一阶模型,利用Simulink对一阶船舶运动模型进行动态仿真,对船舶回转操作和Z形操纵的动态特性进行描述.对试验样本仿真结果进行的定量与定性分析表明,该模型是正确、可行的,对船舶操纵性试验研究具有实际意义.

To further study the ship manoeuvrability, the mathematical model of the linear equation of the ship maneuvering motion was established based on the index numbers such as K, T of reality ship, and Matlab Simulink was used to simulate the linear equation of the ship maneuvering motion. The turning circle operation and ＂Z＂ operation were described dynamically. Quantitative and qualitative analyses show that the proposed model of ship motion is right and effective, which has practical significance in ship maneuvering tests.
