摘要 基于近年来对X型艏与撬冰式船首的研究,设计一种能够兼顾无冰水域阻力特性的新型撬冰式破冰艏。通过数值模拟计算两型主尺度相同但分别具有新型破冰艏与传统球鼻艏的海工辅助船的静水阻力,并进行对比以及通过船模试验进行验证。结果表明,具有新型破冰艏的船舶在设计航速下的阻力更小,为破冰船静水阻力性能与破冰性能无法同时兼顾的问题提供了新的解决思路。 Basing on the study of the X-bow and the upward ice-breaking bow in recent years, a new type of upward ice-breaking bow considering the drag Performance in calm water is designed. Meanwhile, the drag of two types of marine auxiliary ship with the same principal dimension which have the kind of bow and bulbous bow respectively is calculated by numerical simulation to make a comparison, and the calculation is validated by ship model test. The result shows that the ship with the new type of upward ice-breaking bow has less resistance at design speed, providing a new solving method for the problem that the ice-breaking bow cannot take account of the drag performance in calm water and the ice-breaking performance.
