摘　　要：为了研究某新船型的开发以及快速性问题,本文提出并介绍了一种新型小水线面穿浪杂交双体船的构型,首先对其开展了相关的模型拖曳试验,然后基于RANS方法、数值水池以及6-DOF运动模型的数值模拟方法对该船型的阻力性能进行数值计算,通过与试验结果的对比,验证了该数值模拟方法的可行性;同时对该船型在其他不同工况下的阻力性能也进行了数值计算,并对排水量和主尺度相似的WPC和SWATH也进行了数值计算,研究结果表明:对比不同工况下该船型的数值计算结果,发现正浮时的阻力、升沉以及纵倾角都要小于有初始纵倾角的值;在中低速时三种船型的无因次阻力、纵倾角以及无因次升沉差别很小,高速时该杂交双体船的无因次阻力、纵倾角以及无因次升沉都要小于WPC以及SWATH,从而说明了该船型在高速时具有优于同排水量和主尺度的WPC和SWATH的阻力性能。This paper introduces a new type of small waterplane surface-wave piercing catamaran.Relevant model test of resistance was carried out,while numerical simulation was performed in a numerical pool,which is based on RANS method and the 6-DOF motion model.Feasibility of the numerical simulation is verified by a comparison with test results.Performances of the WPC and SWATH with similar displacement and main dimensions are calculated.It is shown that the resistance,the sinkage and the angle of trim of the ship with zero trim are smaller than the ones with the initial trim angle.Angle of trim and dimensionless sinkage of the hybrid catamaran are smaller than the ones of the WPC and SWATH at high speed,and thus the hybrid catamaran has better resistance than the WPC and SWATH with same displacement and the main dimensions.
