| 摘 要： | 为获取拖船在拖曳时的操纵性的变化规律。文章采用MMG船舶运动数学模型的建模思想,建立了六自由度拖船运动数学模型,采用有限差分法,建立了拖缆模型。然后,在此基础上建立将船-缆耦合起来以形成整个系统的运动数学模型,并分别采用龙格库塔方法对船舶运动积分求解,采用后向差分法对拖缆运动进行求解。通过对比仿真计算分析了水面拖船在拖带过程中的加速性能、旋回性能及偏转抑制性能。仿真结果表明在拖船与拖缆的相互影响下,拖船的加速性能和旋回性能有所下降而偏转抑制性能有所增强。

Analysis of maneuverability of towing cable ship system |

| Abstract: | For obtaining the regular rules of a cable towing vessel, the following methods are adopted. Ac-cording to the MMG ship motion mathematical modeling theory, a 6dof ship motion mathematical model was built. And a 6dof cable motion mathematical model was established with finite difference method. Then, a coupling ship-cable system model was established. Finally, the system motion simulations containing accel-eration, turning and zigzag maneuvering were carried out, and the results indicate that the abilities of ac-celeration and turning are decline, but yaw checking ability is enhanced. |
