摘要
对双船拖曳系统的动力学运动特性和受力特性进行研究。通过建立含有阻尼模型的凝集参数方法,求解双船拖曳缆系统的动力学计算模型;将比例阻尼模型加入该动力学模型中,对放缆长度、拖曳速度、双船间距和船舶在波浪中的运动响应等进行计算对比分析,并根据所得结果验证该模型的有效性。通过对具有显著阻尼的双船宽面拖曳系统进行运动学响应计算,给出该系统的运动响应基本规律,为实现高效率的宽面探测活动提供参考。
A study is carried out on the dynamic motion and force characteristics of the dual-ship towing system. By using the lumped parameter method with a damping model, the computation model of the dual-ship towing system dynamics can be solved. By introducing the proportional damping model into the model of dynamics, the ship motion responses in waves under various cable lengths, towing speeds and distances between the two ships could be computed and analyzed and the effectiveness of the model is validated according to the results. By solving the kinematic response calculation of the dual-vessel towing system with significant damping, the basic law of the motion response of the dual-vessel towing system is given, which provides a basis for the realization of high-efficiency wide-surface detection activities.
