摘　　要：文章所研究的船型是以某圆舭船型为母型,采用低内倾干舷和后倾穿浪艏设计,应用减纵向运动组合附体技术生成的新型单体复合船型。文中对该新型单体复合船型开展了水池模型试验研究,试验内容包括静水阻力试验、规则波及不规则波耐波性试验,并与圆舭原船型和常规单体复合船型模型试验结果进行比较。模型试验结果表明新船型比圆舭原船静水阻力性能得到提升,高速36 kns时减阻3%以上,耐波性较圆舭原船得到大幅提升,30 kns平均减纵摇达50%,综合航行性能得到大幅提升,且优于常规单体复合船型。The researched ship is a hybrid monohull based on some round-bilge ship using intilted low-freeboard, wave piercing bow, and longitudinal stability built-up appendage. In this paper, the model test on this new hybrid monohull is researched including resistance test in calm water and seakeeping test in regular and irregular waves. The model test results are compared with the round-bilge original ship and the regular hybrid monohull, and indicate that the resistance performance of the new hybrid monohull is better than the original ship, and the resistance is reduced by more than 3%at 36kns. The seakeeping performance is even better, and the pitch amplitude is averagely reduced by 50%. So the sailing performance of the new hybrid monohull is much better than the original round-bilge ship and even better than the regular hybrid monohull.
