摘要
深V船型较圆舭船型具有优良的耐波性能。在深V船型船首底部加装减纵摇组合附体生成深V单体复合船型可以使其耐波性得到大幅提高,且具有在波浪中高速稳定航行的能力。本文以某千吨级圆舭船型为母型,保持排水量基本不变,生成深V型主船体,再应用减纵摇组合附体技术和尾板技术生成千吨级单体深V复合船型。通过主船体线型设计及组合附体构型和水动力布局的优化组合使单体深V复合船型静水阻力性能与原船型相当,同时耐波性得到大幅提升。经数值模拟和模型试验验证表明,本文提出的复合船型静水阻力与原船型相当,耐波性得到大幅提升,达到预期目标。
It has been indicated that the seakeeping performance of ships with deep-V sections are better than round-bilge ones.Fixing the longitudinal stability built-up appendage on the bottom of deep-V monohull could improve the seakeeping performance while has little influence on resistance performance in waves.In this paper,the 1 000 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 residuary resistance has been reduced effectively,so the total resistance of the hybrid monohull is almost the same as the original ship.It has been indicated by the numerical simulation and 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 is almost the same,and meets the goal.
