减摇水舱固有频率的选取新方法

A New Method for Choosing the Natural Frequency of the Anti-rolling Tank

水舱固有频率是刻划水舱特征的基本参数 .通过比较可控被动式减摇水舱几种常见的固有频率选取方法 ,提出了一种新的选取方法 .指出应从船舶所服务海域的波浪频率变化范围和船舶横摇频率变化范围出发 ,同时考虑其他影响因素 ,确定减摇水舱固有频率 .

The natural frequency is one of the parameters characterizing the feature of the anti rolling tank. Based on the comparative research on the commonly used methods of choosing the natural frequency of the controlled passive anti rolling tank, this paper develops a new method of choosing the natural frequency for the tank, in which selecting the natural frequency of the anti rolling tank should be based on the range of variation of wave frequency of the sea area in which the ship operates, the range of the ships rolling frequency and the other dependent factors.
