摘　　要：将深V船型应用于大型化高速船的实船设计中,采用非线性型线变换生成多样化的型线方案,运用势流CFD方法对各型线方案进行兴波阻力船型优化。通过相同主尺度及设计排水量条件下的船模阻力对比试验,验证了优化后的深V船型可以在保持高傅汝德数Fr阻力性能优势的同时,在低傅汝德数Fr时拥有与圆舭船型相当的阻力性能。运用切片理论对深V船型进行耐波性理论预报,并对预报结果进行耐波性试验验证。试验结果表明,切片理论适用于瘦长型深V船型的耐波性预报。This study involves the design of a high speed vessel with a deep-Vee hull by using a nonlinearhull transformation to diversify the hull forms, then optimizing the hull forms by the potential flow CFD.Model tests which use the same dimension and displacement ship models show that the resistance perfor?mance of the optimized deep-Vee hull is equivalent to the round-bilge hull in its low Froudes number,with it keeps the advantage of resistance performance in high Froudes number. Moreover, the study pro?vides seakeeping predictions for the optimized deep-Vee hull by strip theory, and compares the results ofthe theory predictions with the model test. The results of the model test show that strip theory is able to pro?vide reasonably accurate seakeeping predictions for the thin deep-Vee hull.
