摘　　要：基于iSIGHT优化设计平台,结合SHIPFLOW软件,以最小兴波阻力为目标,构建了一种基于阻力最优的的球首线型优化方法。该方法集成了船型变换方法、阻力评估及优化算法。通过对某内河集装箱船球鼻首区域开展优化,使兴波阻力明显下降,总阻力也随之降低。研究表明,本文的方法适用性较强,对船型设计具有一定的实用价值,在基于CFD的船首线型优化方面具有广阔的应用前景。In this paper,based on iSIGHT multidisciplinary optimization platform and SHIPFLOW software,an optimization method of bow line based on optimal resistance is established to minimize wave-making resistance.The method integrates the bow transformation and automatic generation technology,resistance evaluation and optimization algorithm.The optimization of bulbous bow area at the bow of an inland river container ship is carried out.The results indicated that the wave-making resistance of hull line decreases obviously and the total resistance also decreases.It shows that the method developed in this paper has strong applicability,has certain practical value for hull form design,and has broad application prospect in bow line optimization based on CFD.
