【摘要】 研究拖船通过一弹性绳索带动被拖船运动，基于水平面内操纵运动方程组，编制了计算程序．该程序能作两类预报，一是被拖船在不同初始条件下的运动时域数值模拟，二是求解临界点状态量，并依照摄动理论对临界点状态的稳定性作出判断更多还原

【Abstract】 This paper studied manoeuvring motion simulation of towed ship by an elastic rope.Based on the equations of manoeuvring motion system computer program was processed,that can complete two sorts of predictions.One of which was towed ship motion simulation in time domain at different initial conditions.The other was obtaining a solution of state valume at critical points.According to perturbation theory,the state stability near those points can be decided.更多还原
