摘要
冰区航行船舶操纵仿真训练平台的建立,可完善现有航海操纵模拟器的操船训练功能。针对船舶冰区航行特点,运用微元法建立船舶冰区航行动态数学模型,并将该模型加载到航海操纵模拟器的平台开发中。利用微元法对船舶与冰层接触部分进行分析研究,得出船舶纵向、横向和垂向3个方向上冰层对船舶的冲击速度,从而得出船舶各个方向上受到冰块冲击力的大小,并将其加入到分离型船舶操纵运动数学模型中。通过对给定船型进行旋回仿真实验,实验结果表明本文建立的船舶冰区航行运动数学模型的误差在20%以内,可以应用于现有的航海操纵模拟器开发应用当中。
In order adding ice sailing ship man to improve the operation of existing ship bridge simulator training function, euvering simulator training platform for ice sailing ship characteristics, the use of the ship to arrive at the ship in all directions by the impact of the size of the ice and add them to the separation-type ship maneuvering mathematical model. Performed by a given ship cycle simulation experiment results show that the establishment of a ship sailing in ice sports mathematical model error less than 20% , can be applied to existing development and application among ship bridge simulator.
