钢质海洋渔政船空船重量与重心估算方法研究

Study on lightweight and center of gravity estimation for sea-going steel fishery administration ships

在实船资料统计分析和基于船舶基本原理基础上,提出了适合渔政船设计初期空船重量及重心的估算公式,以此分析、整理出的回归方程更具有针对性。将空船重量、重心高度、重心纵向位置的公式计算结果与实船倾斜试验所得值相比较后发现,相对误差符合工程要求,重心纵向位置值亦在允许范围内。本估算方法可以给设计者以前期估算参考。

The sea-going steel fishery administration ship is to be standardization and humanization. The esti- mation of lightweight and center of gravity is essential for the preliminary design. This paper collected most of data of existing fishery administration ships, and analyzed lightweight and center of gravity of fishery adminis- tration ships, then put forward formulas for calculating lightweight and center of gravity. The empirical equa- tions was based on the ship design theory and regression analysis of fishery administration ship data. Compared the calculated result with the real test one, the relative error is adequate for preliminary design.
