舰船系泊缆绳的受力控制系统研究

Research on the force control system of the mooring cable of ship

大型船舶和作业平台在海上开展作业时,都需要通过一定的方式进行平稳的定位,而锚泊定位是最传统而有效的海上定位方式。船舶或者作业平台采用锚泊定位时,不可避免受到海浪作用力、海风作用力、船舶振动等因素的影响,导致船舶定位精度降低,严重的甚至出现系泊的缆绳发生断裂和结构破坏,造成经济损失和人员伤亡。为了提高船舶和作业平台的系泊(或者锚泊)稳定性、安全性,本文将研究重点放在船舶系泊的缆绳受力控制系统,分析船舶系泊时缆绳的非线性动力学特性、稳定平衡、缆绳振动等问题。在Matlab平台中设计了缆绳的受力控制系统,并对系泊缆绳的力学特性进行了仿真分析和有针对性的优化。

In a certain way, and anchorage positioning is the most traditional and effective way to locate the sea. When the ship or operation platform is anchored, it is inevitably affected by the influence of wave force, sea wind force, and ship vibration, which leads to the reduction of the positioning accuracy of the ship, and even the fracture and structural damage of the mooring cables, resulting in economic loss and casualties. In order to improve the stability and safety of mooring(or anchoring) of ship and operating platform, this paper focuses on the force control system of the cable of the mooring ship.Through the analysis of the nonlinear dynamic characteristics, stability balance and cable vibration of the ship mooring, this paper designs the cable in the MATLAB platform. The force control system is analyzed and the mechanical characteristics of mooring rope are simulated and optimized.
