摘　　要：船舶建成试水后,通常会给出该船舶的操纵试验旋回圈参数。以Matlab软件中的Simulink模块工具,遵照船舶运动坐标系的构建方法,根据船舶操纵性能指标及船舶运动数学模型,搭建出船舶运动轨迹仿真模型。该模型能够快速地计算出船舶K、T值,且仿真出船舶在转向或者做旋回时,船舶旋转枢心点(P点)和船舶尾部(S点)的移动轨迹图;利用船舶在转向时随着时间变化的速度v(t)作为输入信号,以随时间变化的有效舵角δ(t)和漂角β(t)为输入信号,提高了船舶运动模拟仿真的逼真度。When a ship is built and tested in water,the maneuvering test cycle parameters of the ship are usually given.Based on the ship’s maneuverability index and motion mathematical model and following the construction method of ship’s motion coordinate system,the simulation model of ship’s motion trajectory is built by using Simulink module tool in Matlab software.The model can quickly calculate the K and T values of the ship,and simulate the trajectory of the ship’s pivot point(P point)and stern point(S point)when the ship is turning or making a circle.In addition,this study uses the time-varying speed[v(t)]as input signal and the time-varying effective rudder angle[δ(t)]and drift angle[β(t)]as input signal to improve the fidelity of ship motion simulation.
