基于目标的甲板梁拱设计研究

Research of Design of Deck Camber Based on the Goal

以油船和散货船为对象,介绍了甲板梁拱的型式和作用,并对梁拱的设计进行了探讨。对于具有梁拱的船舶的甲板板总纵弯曲应力计算,文章给出了一个有效的计算公式,也详细分析了甲板企口的设计。结果显示,对于甲板梁拱的设计,虽然目前没有任何规范给出明确规定,但它对整个船舶设计的影响是深入和全面的,应从基于使用目的和方便施工等目标进行综合考虑。

Based on oil tankers and bulk carriers, the paper introduces in detail the types and action of deck camber, and discusses the design of the deck camber. For the purpose of ships with deck camber, the paper presents an efficient formula for the calculation of hull girder longitudinal bending stress for the ship. Also the outstanding of sheer strake is analyzed in detail. The conclusion shows that though there is no rule giving a clear statement, the influence of the design of deck camber on the whole ship is deep and wholly. The design should be based on the goal and convenient construction to do comprehensive consideration.
