摘要
为了研究母船回转过程中拖体运动规律和拖缆构形的变化情况,采用凝集质量法建立二级深拖系统数学模型,计算分析母船不同回转参数下拖体运动状态的变化规律,得到拖缆的瞬态和稳态构形图。仿真结果表明,在360°稳态回转和360°单圈回转条件下,母船回转半径和拖曳速度均对一级拖体和二级拖体的深度变化及稳态特性有显著影响。母船小半径、大速度回转时,两级拖体的回转半径和深度变化较大,应予以特别关注。
In order to explore changing conditions of the motion characteristics of towed vehicles and cable configuration during towing ship turning maneuvers, the mathematical model of two-part towed system is established using lumped mass method. The change rule of motion state of the two towed vehicles is analyzed using simulation method, and the cable configuration at both transient and steady state is obtained. The result shows that the turning radius and towing speed of the towing ship has great influence on the depth change and steady properties of both towed vehicles during 360° steady-state and a single 360° turning maneuver. Turing radius and depth of the two towed vehicles changes greatly when mother ship turns at a small radius and large towing speed, which should be paid special attention.
