半串联造船中起浮和落墩浮态问题研究

Study on Floating State of a Ship during Its Rising and Falling in Series Shipbuilding

本文研究了半串联造船中半船和整船起浮、移位和落墩的安全浮态问题 ,给出了最大安全艏艉吃水差的计算方法和公式。分别用半船和全船实例进行了计算 ,对计算结果进行了分析 ,得出了非常实用的结论。本文可指导船坞造船 ,特别是编制船坞工艺技术文件时参考 ,并可改变对艏艉吃水差的传统概念 。

In this paper,the safe floating state of a half ship and a complete ship during its rising,replacing and falling in the process of series shipbuilding is studied,a calculation method and formulation for the largest safe difference between the fore draft and the aft draft is derived and used for calculation of a half ship and a complete ship taken as example.Calculation results are analyzed and very practical conclusions are derived therefrom.The paper may be of reference value for in-dock shipbuilding,and especially for preparing the in-dock process document,and may change the traditional concept of the safe difference between the fore and aft drafts.
