【摘要】 船舶在波浪中的响应一直被船舶工程师广泛关注。本文以Wigley船为对象,采用线性回归计算船舶在规则波中运动的附加质量,采用刘易斯法计算阻尼系数。以新切片理论为基础建立和求解频域内的垂荡和纵摇的耦合运动方程,得到船舶在频域中的运动响应和波浪载荷,并与三维网格法的计算结果进行比较,表明这是一种可靠的、简单快捷的计算船舶在波浪中响应的方法。更多还原

【Abstract】 The ship motion response characteristic in the wave is always concerned widely by the shipping engineers.For the simulation of motions of Wigley ship in regular wave,the linear regression method is applied to compute the added mass and obtain the damp coefficient by lewis’s method.The ship heave and pitch coupling motion equations are established by the new strip theory and the wave exciting force and motion response are derived by solving the equations in the frequency domain.The good agreement with the 3-D grid method shows this method is a simple and quick compute method to predict the ship motion response characteristic in the wave.更多还原
