船舶参数横摇非线性力学特征数值分析
|
摘要
为研究船舶参数横摇发生的力学机理,文章基于计算流体力学方法,对DTMB 5512船模规则波顶浪航行时的参数横摇运动进行了数值模拟。模拟结果表明:参数横摇复原力矩曲线会随横摇角增大而出现2个拐点,呈现出先增大、后减小、再增大的非线性特征;其零点、拐点及最大值点可以分别用垂荡、纵摇及船/波相对位置进行表征。文中方法实现了船舶参数横摇力学特征的数值分析,可为船舶波浪中的完整稳性评估提供新的方法。
In order to study the mechanical mechanism of parametric rolling, CFD approach study for the DTMB 5512 surface combatant is presented. The simulation results show that the parametric rolling restoring moment curve shows two inflection points with increase of the rolling angle, which shows the non-linear characteristics of first increasing, then decreasing, and then increasing. And its zero point, inflection points and maximum point can be characterized by pitch, heave and ship/wave relative position, respectively. The method of this paper realized the analysis of the mechanical characteristics of parametric rolling, and provided a new way for vessel's complete stability evaluation in waves.
