4000t级单体深V复合船型阻力及耐波性能

单体复合船型是基于减纵向运动组合附体技术研发的高耐波性船型。基于性能优良的圆舭船型进行深V船型线型设计,再应用减纵摇组合附体技术,生成深V单体复合船型,使其耐波性得到大幅提高的同时对静水阻力影响较小。本文基于某四千吨级圆舭船型,经过深V改造生成深V主船体,并设计匹配的首部组合附体和尾板,生成四千吨级单体深V复合船型。通过合理的主船体和附体构型设计和水动力布局,有效降低深V船型兴波阻力。经模型试验验证表明该单体深V复合船型对静水阻力影响不大,耐波性得到大幅提升。

Research on Resistance and Seakeeping Performance of 4000 tons Deep-V Hybrid Monohull

Hybrid monohull is a kind of high seakeeping performance vessel based on longitudinal stability built-up appendage technology. Fixing the longitudinal stability built-up appendage on the bottom of deep-V monohull could improve the seakeeping performance and influence the calm water resistance little. In this paper, the 4000 tons hybrid monohull was designed basing on the round-bilge monohull with the same tonnage using the built-up appendage and stern flap technologies. By the logical lines, appendage and stern flap designation, the wave making resistance has been reduced effectively. It has been indicated by the model test that the seakeeping performance of the hybrid monohull studied in this paper is much better than original ship while the resistance in calm water of the two ships are almost the same.
