摘要随着全球经济的日益发展,环境问题也日益突出,为我们所重视。船舶行业是能源大消耗的产业,对燃油的需求非常大。所以,本次论文选择风帆助推船方面的研究,通过风帆,利用风能,节省能源的消耗。本次论文研究风帆助推船,通过在船上加装风帆,利用风能来实现船舶助推地作用主要通过如下研究:(1)风帆的设计选取、计算风帆面积、重量、以及确定出帆的位置。(2)计算装帆后的船舶初稳性高、吃水变化。(3)干舷校核。(4)新的初稳性计算。对12500DWT 散货船的分析,得到单个风帆的面积为 726.085m2,现有的大多数船的展弦比在1.0-1.2 范围内, 则取帆高23.76m,帆宽 19.8m,计算出单个帆的重量 136.38t.放置风帆在 75 肋位和 121 肋位处。经计算,加帆后船的吃水增加0.099m,而纵倾角正切过小,认定加装风帆对船舶的影响是平行沉浮。干舷校核也满足夏季最小干舷。最后便是对四种工况下的稳性计算,得出符合规范要求。61821

Abstract With the development of the global economy, the environmental problems arebecoming more and more serious, which is the focus of our attention.Shipbuildingindustry is a major energy consuming industries, the demand for fuel is very large.Therefore, this paper chooses boost research vessel sails aspect, by sail, wind energy,saving energy consumption.The thesis sail boat propelled by sail on board the installation, the use of windenergy to act as ship propelled primarily by the following research:(1)sail design selection, calculation of sail area, weight, and determining theposition of the sail.(2)Calculated after the installation of sailing ships high initial stability, draftchanges.(3)Check freeboard(4)The new initial stability calculation12500DWT analysis of bulk carriers to obtain a single sail area is 726.085m2, mostof the existing vessel aspect ratio in the 1.0-1.2 range, then take the sail high 23.76m,sail wide 19.8m, calculated single sail weight 136.38t. place ribsWindsurfing 75-bitand 121-bit at the ribs.After calculation, plus sail boat after the draft increased 0.099m,and the pitch angle tangent is too small, it shall influence the installation of sailingship are parallel ups and downs.Freeboard check also meet the minimum summerfreeboard. Finally, there is four kinds of conditions of stability calculations, obtainedin line with regulatory requirements.
Key words : Sail-assisted ship; Sail design; Floating state; Stability
