| 摘 要： | 对规则波中船舶横摇稳性的特点进行了分析和介绍,提出一种比较可靠的研究船舶在规则波中横摇时的复原力臂方法.基于切片理论,利用三个坐标系之间的转化关系,建立任意规则波中重力与浮力平衡及纵倾力矩为零的瞬时静平衡方程,同时提出任意规则波中船体各横剖面左右舷与波面一组或多组交点的求法及各浸水剖面面积的通用计算法,并基于Froude-Krylov假说得到船舶在波浪中的复原力臂.通过对一艘渔政船的各种瞬时状态的计算,得到波浪中船舶的复原力变化特性及影响波浪中复原力变化的重要因素.

| Abstract: | In this paper,the characteristics of roll stability of ship are introduced and analyzed,and an accurate study method of righting arm when ship rolls in waves is presented.A method of calculate one set or more than one set of intersection between ship and any regular wave is presented base on transform of three coordinate systems.While calculating instantaneous wet surface,the balance between ship weight and buoyancy and the balance of trim are considered.At the same time,one more current method of calcu-lat... |
