摘　　要：为了模拟拖轮协助大型船舶的操纵过程,采用MMG船舶运动数学模型的建模思想,建立拖船和被协助拖船的运动数学模型,并采用基于拖轮缆索和碰垫的形变-应力特性建立拖缆和碰垫力数学模型,由此组成交互式拖轮辅助系统。然后以具体实例进行静水中拖带和顶推仿真,并给出两船在不同协作方式下的航迹、船首向、航速、拖缆和碰垫力变化的仿真结果。仿真结果符合实际规律,可应用于大型船舶操纵模拟器。In order to simulate the handling process of large ship with tugs assistance,models of the tug and the ship being assisted were built based on the theory of MMG ship motion mathematical model.And,the hawser and fender force mathematical model based on deformation stress characteristics was adopted.Sequentially,the interactive tug assistant system was established.And then the simulation of towing and pushing in still water was carried out based on specific examples,and the simulation results of track,heading,speed,towing and pushing force of the two ships under different cooperation modes were given.The simulation results accord with the actual law and can be applied to large-scale ship maneuvering simulator.
