Having analyzed the experiences of bulb designs at home and abroad, the author designs a satisfactory bulb for a 15000 dwt multipurpose ship which is of block coefficient 0.736: The result of the ship's self-propulsion test has shown that: It can increase 0.4 knots speed in full-load condition compared with the original non-bulb ship and receives the benefit of resistance reducing over the low speed range. The design methods and the bulb effect line given in the paper are a valuble reference for the bulb design....

本文介绍方形系数0.736、载重量15000吨多用途船的球首设计。鉴于中速中型船舶球首设计的资料较少,且难以获得明显的减阻效果,笔者通过综合国内外球首研究经验,成功地对15000吨多用途船选择了优良球首,经船模自航试验证明,该球首在满载时比原无球首船提高航速0.4节,而且在整个低速范围内都有减阻效果。文中给出的设计方法、球首效果线等对球首设计与研究具有一定的参考价值。

In this paper orthogonal analysis method combined with computer simu-lation is used in the discussion of technoeconomic problems of the sea-river-thro-ugh multi-purpose cargo ship under varied operating and environmental condi-tions.Some valuable conclusions are obtained in this respect.On the basis ofanalysis it is clear that sea-river-through multi-purpose cargo ships can be deve-loped with good techno-economic feasibities.Development of sea-river-throughmulti-purpose cargo ships satisfies the requirement...

In this paper orthogonal analysis method combined with computer simu-lation is used in the discussion of technoeconomic problems of the sea-river-thro-ugh multi-purpose cargo ship under varied operating and environmental condi-tions.Some valuable conclusions are obtained in this respect.On the basis ofanalysis it is clear that sea-river-through multi-purpose cargo ships can be deve-loped with good techno-economic feasibities.Development of sea-river-throughmulti-purpose cargo ships satisfies the requirement of foreign trade marine trans-portation.Through comparison a kind of sea-river-through multi-purpose shipmould is proposed for better operating economics.

本文针对长江沿线外贸运输的发展,提出一种用正交分析和计算机仿真相结合的方法,对设计在多种营运环境下工作的江海直达多用途船进行技术经济论证,从而得出了一些有参考价值的结论.分析比较表明,在预测的营运经济条件下,多用途江海直达船具有良好的经济性和技术可行性.开发江海直达多用途船可满足外贸运输的要求.经过比较,最后提出了一种营运经济性较佳的船型.

The 21000 DWT multi-purpose ship is a liner of shanghai Ocean Shipping Company on south America route.According to the comprehensive analysis on voyage, ship numbers and schedule.the main engine delivered power of 7239. 75 kW is required to reach the ship speed of 16. 5 kn. when taking sea margin 15% into account. Aiming at this high ship speed index given by the ship owner. the bulhous bow design and the optimization tests on stern straightening ducts and rudder bulbs were carried out. The design idea and test...

The 21000 DWT multi-purpose ship is a liner of shanghai Ocean Shipping Company on south America route.According to the comprehensive analysis on voyage, ship numbers and schedule.the main engine delivered power of 7239. 75 kW is required to reach the ship speed of 16. 5 kn. when taking sea margin 15% into account. Aiming at this high ship speed index given by the ship owner. the bulhous bow design and the optimization tests on stern straightening ducts and rudder bulbs were carried out. The design idea and test results are introduced in the paper.

21000t多用途船是上海远洋公司在南美洲航线上的定期班船,根据航程、船只数量、航班期的综合分析,要求船舶在主机输出功率7239.75kW,含有15%海上功率储备时,航速达到16.5kn。为达到船东提出的先进航速指标,进行多次球首设计及尾部前置导管舵球的优化试验。介绍其设计思想及试验结果。
