摘　　要：基于船舶推进和船舶操纵性理论，建议了一个计算紧急停船运动的数学模型，并对其中的螺旋桨水动力和力矩提出了一种新的处理方法．利用该数学模型对数十艘实船进行了紧急停船仿真计算，并与相应的实船试航、实船试验实测结果进行了比较，吻合很好．验证了该数学模型的正确与有效，可用于计算船舶的紧急停船运动与预报船舶的紧急停船性能．A mathematical model of computing ship motion in crash stopping is proposed and a new method for dealing with hydrodynamic forces and moments of propeller based on the principle of ship propulsion and manoeuvrability is put forward in this paper. With this mathematical model, simulative computations of ship motion in crash stopping on scores of ships were carried out. Good agreement has been arrived at comparing with the results of the trials and experiments on ships. The correctness and validity of the mathematical model are verified. This proposed mathematical model can be used to compute the ship motion in crash stopping and predict the performance of the crash stopping ability.
