| 摘 要： | 文章在建立减摇水舱内气体和液体两相流动的运动模型基础上,研究了水舱顶部气体连通道的横截面积大小与水舱内液体振荡参数之间的关系,通过调节截面开口控制水舱内液体运动固有频率,使之与船舶横摇频率相适应.分别利用被动式PD控制和模糊控制实现气阀开关式和气阀开口连续式两种调频策略.仿真研究表明,两种调频策略均使可控被动式水舱的有效减摇范围拓宽,并在不同的频率范围内有各自的优势.

| Abstract: | Mixed motion model of air flow and liquid flow was established in the paper.On the basis of the model,relationship between the sectional area of air duct and liquid flow characteristics was researched.When the ship's natural frequency varies with its sailing condition,it is practical to adjust the tank's natural frequency by changing the area of air duct to follow ship's natural frequency.In order to make the frequency self-regulation available,bang-bang strategy and continuous strategy was achieved through... |
