影响半潜船初稳性高度限值因素及其作用机理
The influencing factors of semi-submersible vessel’ s metacentric height limits and mechanism of action
摘要
Abstract
To explore the influencing factors of semi⁃submersible vessel’ s metacentric height limits and their mecha⁃nisms, the original dynamic balance formula was modified to form a new formula suitable for semi⁃submersible ves⁃sel’ s metacentric height limits. By this method of the variable control parameters, the parameters including special heavy cargo’ s weight, height of center of gravity, wind area, height of wind pressure center, wind speed on the sea, friction coefficient, etc. were changed to quantitatively calculate their influencing degree on the metacentric height limits of semi⁃submersible vessels. Finally, the changing rules of semi⁃submersible vessel ’ s metacentric height limits were analyzed under different influencing factors in combination with the practical status of special heavy cargo, verifying that the formula for the metacentric height limits is reasonable.关键词
