【摘要】 以欧拉角描述船舶的摇摆运动，考虑规则波浪力及船舶受定常力矩的情形，将水动力展为Ｔａｙｌｏｒ级数，利用欧拉动力学方程推导出船舶横摇与纵摇二自由度耦合的非线性运动方程，为船舶内共振运动响应动力行为分析奠定基础．更多还原

【Abstract】 In this paper,the Euler angle is used to describe the rotation of a ship.After employing Taylor series expansions to determine the hydrodynamic load on the hull of a ship,and considering the wave excitation moment and a stationary moment,the nonlinear coupling equations for ship rolling and pitching motions can be formulated by means of the Euler dynamic equation.This work is the basis of the dynamic behaviour analysis of the internal resonance of a ship.更多还原
