As a result , the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion , taking into account of the influence of the environmental factors , such as the wind , wave and current , establish a practical and complete system for the prediction of ship maneuvering motion . in this paper , the opengl virtual reality simulation technique is introduced into the field of ship maneuver and control , and using the mmg mathematical model , the three dimensional dynamic simulation system of the ship motion is established and good results are achieved . in the process of the system development , firstly , the maneuvering motion equations for ship in the still water are established , based on the mmg module mathematical model and serial experimental result 在系统开发过程中,首先采用mmg分离式数学模型及相关的系列化试验结果,建立单桨单舵海洋运输船舶在静水中的船舶操纵运动方程,并编制计算程序,经与试验结果比较,证实了计算结果的正确性;为了解mmg数学模型中模型参数变化对操纵性指数的影响程度,作者在上述已有程序基础上,对有关模型参数进行偏移修正,探讨了相应参数变化后的操纵性指数,对船舶操纵性指数对模型参数的灵敏度进行了详细的分析与探讨,所得结论与工程实际相吻合,具有实际应用价值,并为进一步提高船舶操纵性预报的精度打下了基础;然后,在已有的船舶静水操纵运动模型基础上,考虑双桨双舵的影响,建立了内河双桨双舵船舶的操纵运动模型;最后,综合考虑风浪流作用力的影响,进行了船舶的操纵运动仿真计算。
