| 摘 要： | 动力定位系统（dynamic positioning system）是一种闭环自动控制系统，采用推力器来抵抗风、浪、流等作用在浮体上的境力，使其保持在所要求的位置上。船舶的风和流作用力由经验公式求得，波浪力主要考虑二阶漂移力，由三维势流理论的直接积分法求得。通过模拟仿真，表明其结果能够用于船舶动力定位系统研究。

| Abstract: | The dynamic positioning system is a sort of autocontrol system which resists against the disturbing forces by wind, wave and current with the help of thrusters on the floating structure. The aim of the system is to keep the structure on a specified position. In this article, empirical formulas are adopted to acquire the current and wind loads on the vessel. The wave force component named the second order wave drift force is mainly considered, and it's calculated by the direct integrate method of the 3-dimensional potential theory. Finally, the results of simulation show that the model can be applied to the dynamic positioning system. |
