【摘要】 船舶的港内自动操控是当前船舶运动控制领域的一大难点,这主要是由于船舶在港内浅水域中航行时,水深以及航速等条件的改变,其自身水动力将发生明显变化,由此引起的船舶运动不确定性将对控制系统的设计造成困难,并影响船舶的港内操纵安全。本文以进行靠泊低速航行的船舶为研究对象,基于三维势流理论计算得到船舶附加质量与辐射阻尼等频域水动力参数,并对不同波浪频率、相对水深以及航速条件下的频域水动力系数变化规律进行了研究与分析,为进一步研究港内船舶自动操控提供了基础。更多还原

【Abstract】 The auto control of ships in port is a difficulty in the ship motion control field,due to changes in water depth or vessel speed,its hydrodynamic force will change significantly which will affect the safety of ship handling.In this paper,the ship at low speed in shallow water is studied and the hydrodynamic parameters in the frequency domain of the ship are calculated based on the three dimensional potential flow theory.The variation law of frequency-domain hydrodynamic coefficients under different wave frequencies,relative water depths and ship speeds is analyzed,which provides a basis for further study of ship auto control in shallow water.更多还原
