【摘要】 作为水下拖缆实时控制策略设计的重要前提,对水下拖缆的动力学特性掌握至关重要。对于长达数千米的水下拖缆,采用计算机仿真技术对其研究,在成本上和效果上都有着比较理想的结果。在Ablow和Schechter[1]的经典模型基础之上建立三维拖缆动态模型,采用广义α算法对其求解。通过计算机仿真程序编译,实现对拖缆在拖船变速直线运动和升沉运动工况下的动力学特性仿真研究,为深入制定拖缆控制策略提供了良好的依据。更多还原

【Abstract】 As an important premise of the design of underwater towed cable real-time control strategy,the study on the dynamic characteristics of underwater towed cable is crucial.Due to the towed cable is usually about thousands of meters long,using computational simulation technology to study cable brings benefits on the cost and the efficiency of the study.In this paper,a three dimensional dynamic towed cable model is established on the basis of the classic model set by Ablow and Schechter[1].The model was solved in generalized-α algorithm.By programming,the simulation of dynamic characteristics of towed cable in towed boat’ s speed changing motion and heaving motion is accomplished,which contribute to the further study on control strategy of towed cable.更多还原
