摘要
通过船舶线型的设计与研究 ,进一步探明了船型与船形之间的有机联系 ,以及船舶线型的优劣对航速或所需主机功率 ,即对能耗的影响是相当大的。研究表明 ,同样主尺度要素下采用不同的船形 ,收到功率的比差可达2 0 % ,这种仅靠船舶线型本身改善而取得的节能效果相当可观。同时 ,还研究了不同的艉部船形对伴流场及艉部激振的影响 ,提供了球艏及艉部线型某些参数的选择范围 ,可供设计参考。
The design and research of ship lines are carried out in this paper.The organic connection between ship type and ship form is certified.The larger influence of ship lines on ship speed or the power required is indicated.Under the same principal dimensions and coefficients,the scale factor of delivery power may reach 20%,if the different ship forms are used. This effect of saving energy is considerable,depending only on improvement of ship lines itself. Moreover,the influence of stern form on wake field and excitation vibrations is also studied.A selective range of some factors for bulb bow and stern lines is provided for reference.
