摘　　要：探讨了平头涡尾船型阻力性能及其与常规船型阻力性能的联系.用运动状态下的水线长和等值船型,提出了平头涡尾船型的阻力模型.据此,运用船舶流体力学的基本观点对平头涡尾船型及其相对航速时所对应的等值常规船型进行了分析,建立了平头涡尾船型与常规船型的对应关系,论述了平头涡尾船型减阻的机制和规律;并给出实船试验结果.The relationship between the resistance performance of a shipform with flat bow and cochlea-channeled stern and that of conventional shipforms is investigated. A resistance model for a shipform with flat bow and cochlea-channeled stern is presented by employing such concepts as the waterline length and equivalent shipform under moving conditions. The shipform with flat bow and cochlea-channeled stern and the corresponding equivalent conventional one having the same Fn are studied with fluid mechanics of ships. The correlation between the two shipforms is proposed and the mechanism of resistance reduction of the new shipform is discussed. The results of model tests and experiments on full-scale ship are giv-en.
