摘　　要：为了更加便捷、高效地开展拖曳系统动力学研究,为水声测量技术提供准确有效的阵型位置,设计了一种小型水下拖曳系统动力学原理样机,并运用基于MapInfo软件的轨迹提取方法,在回转直径为0.50m条件下改变拖曳速度、拖缆长度,开展了拖曳系统U型回转运动实验。通过对实验数据的提取分析定义了拖缆回转弯曲参数,结果表明:当弯曲参数较大时,拖缆回转中轨迹弯曲明显,且受到拖曳速度变化影响较大;当弯曲参数较小时,拖缆回转中轨迹弯曲较弱,且受到拖曳速度变化影响较小。In order to make the study of towing system dynamics more convenient and efficient,and provide accurate and effective position for underwater acoustic measurement technology,a small principle prototype of underwater towed dynamics system is designed,and a trajectory extraction method based on MapInfo software is put forward,and assuming that the rotating diameter is 0.50 m,U-turn maneuver experiment of the towed cable system is carried out by changing towing speed and the length of the towing cable.Then towing rotary bending parameter is defined.The experimental results show that when the bending parameter is large,the trajectory of the towed cable is very obvious du-ring the U-turn process,and is influenced by towed speed;however,when the bending parameter is small,this trend is weakened.
