大型集装箱船参数横摇模型试验和数值模拟研究

以4000TEU集装箱船为研究对象，通过系列自航模型试验，确定其在迎浪规则波中发生参数横摇的限界。试验结果显示：在迎浪规则波中，参数横摇通常发生在波浪遭遇周期为横摇固有周期一半的附近；对应不同遭遇频率时参数横摇的发生，存在一个临界波高；航速的增加和舭龙骨的安装将使参数横摇发生的临界波高增加；当有初始干扰时，参数横摇发生的临界波高较小。而且，数值模拟结果与模型试验结果比较吻合。

Parametric rolling model test and data simulation research on large container ship

A 4000TEU container ship has been taken as the research object,and the boundary of its parametric rolling in head sea regular waves has been decided through a series of self-propelled model test.The test result shows that: in regular head wave,parametric rolling often happens when the wave encounter period is about half of the natural rolling period.As far as different encounter frequencies are concerned,there is a boundary wave-height for appearance of parametric rolling;increase of velocity and equipment ...
