【摘要】：船体结构重量关系到经济性与环保性,是衡量船舶设计方案优劣的重要指标,为提高超大型船舶的市场竞争力,有必要开展超大船体轻量化设计。以一艘32万载重吨超大型油船为例,根据油船分舱布置的要求,在主尺度与船型确定的情况下,以降低总纵弯矩、减轻船体结构重量为优化目标,通过装载、完整稳性、破舱稳性、溢油指数、总纵强度的计算,对比分析多型式的分舱方案。重点研究变边舱分舱方法对降低总纵弯矩的效果及其规范适用性,分析变边舱分舱方案中的内壳舭部斜升角对总纵强度的影响,得到一型可同时降低在港状态中拱弯矩、航行状态中拱弯矩与中垂弯矩的变边舱分舱方案,以期应用于超大型油船船体结构的轻量化设计。
[Abstract]:The weight of hull structure, which is related to economy and environmental protection, is an important index to evaluate the advantages and disadvantages of ship design scheme. In order to improve the market competitiveness of super-large ships, it is necessary to carry out lightweight design of super-large hull. Taking a 320000-ton super-large tanker as an example, according to the requirements of the subdivision arrangement of the tanker, under the condition that the main scale and the ship form are determined, the optimization objective is to reduce the total longitudinal bending moment and lighten the weight of the hull structure, and to achieve complete stability through loading, Break stability, oil spill index, total longitudinal strength calculation, comparative analysis of various types of subdivision schemes. The effect of variable edge subdivision method on reducing total longitudinal bending moment and its applicability are studied. The effect of bilge angle on total longitudinal strength is analyzed, and the results show that one type can reduce the bending moment of arch in port at the same time, and the influence of bilge angle on total longitudinal strength is analyzed. In order to apply to the lightweight design of the hull structure of the super-large oil tanker, the variable side cabin subdivision scheme of the mid-arch bending moment and the mid-vertical bending moment in the navigation state is proposed in this paper.
