为研究海流作用下舰船锚链的运动响应，在锚链微元运动控制方程基础上，计入其受到的海流作用力和弹性形变等因素影响，建立锚链运动模型并进行了仿真，进而与经典悬链线方程法的计算结果对比分析。结果表明，海流作用会对锚链悬链段长度、顶端位移以及各点处的张力等产生影响，且这一影响将随着海流流速的增大而愈加明显，实际工程中应予以考虑。建立的舰船锚链运动模型及结论分析，对舰船锚泊安全的理论研究和工程实践具有一定参考价值。
Considering the influence of current force, elastic deformation and other factors, a motion model of the anchor chain is established to study the motion of anchor chain in current on the basis of the motion control equation of the chain element. The simulation results of the motion model are compared with the calculation results of the classical catenary equation. The results show that current will lead to the length of the catenary chain, the displacement of the top and the tension at each point increasing. With the current velocity increasing, the impacts are more and more significant, which cannot be ignored in the actual project. The obtained motion model and conclusion analysis provide reference for the theoretical study and engineering practice of anchorage safety.
