摘　　要：进行了船舶在横向规则波中舱室破损进水的二维时域模拟,采用准静态法,认为所有进水液面为水平,进水过程考虑破口内外液面变化,应用简化的水动力模型(伯努利方程)计算进水体积及进水倾斜力矩.考虑波浪静水压力作用,研究横向规则波频率、波高、破口位置对船舶破舱进水横摇运动时历影响.A numerical method for simulating the roll motion of damaged ships in time domain in beam regular waves is developed This method based on the equations of roll motion of the ship. In this method, the well-established classical hydrodynamic formulae are applied to evaluate the quantity of the flooding water and its resultant rolling moment. The water flooded into the damaged compartment is assumed to settle down instantaneously with a flat surface paralleled to the mean sea level, and the hydrostatic pressure of the incident wave is taken into account. Then effects on the course of flooding and history of roll motion due to variations of the frequency and height of the incident waves and the height of the opening are investigated
