摘要
在船舶耐波性研究中,海面上的海浪以及船舶自身等因素对船舶产生影响,导致船舶出现复杂的摇摆运动.这种摇摆运动及其产生的动力效应在一定程度上降低船舶的稳定性和安全性.船舶的横摇和纵摇运动在船舶坐标系的6个自由度中对船舶摇摆运动影响最大,文中以欧拉角描述船舶的摇摆运动,对船舶受力情况进行分析研究,以Hamilton原理为基础,建立了假设船舶参数下纵横摇耦合运动的数学模型,并利用MATLAB进行了数值分析,为以后的船舶减摇控制研究提供参考.
In the study of ship＇s sea-keeping performances,waves of the ocean,the ship itself and other factors will affect the ship and lead to complex rotation motions. To some extent,the rotation motions and its dynamic effects will reduce the stability and safety of the ship. Rolling and pitching motions of the ship are the biggest effect on the ship＇s rotation motions of the six degrees of freedom in the ship＇s coordinate system. In this paper,the Euler angle is used to describe the rotation of a ship. After analyzing the force condition of ship,we establish the mathematical model of the ship＇s pitching and rolling coupled motions for ship parameters based on the Hamilton principle and conduct numerical analysis by using MATLAB. This work is the basis of the ship roll stabilization control.
