摘要

摘要: 快艇在高速航行时会产生剧烈的艏部兴波和干舷淹湿问题，通常需要采用适当的压浪措施来控制这些不利因素。为进一步研究干舷压浪技术在高速艇上的应用效果并与船艏压浪技术进行对比，基于某一细长高速穿浪船，对比这2种压浪技术对船体兴波、淹湿、运动、稳性和高速下横倾回复力矩的影响。船体淹湿、阻力和船体运动通过求解URANS方程和使用动网格技术获得，高速下的横倾回复力矩也通过求解URANS方程获得。计算结果表明，2种压浪技术均能有效控制船体淹湿，但干舷压浪设计能在船长范围内控制船体淹湿并具有更好的初稳性，在高速下也有更大的横倾回复力矩。自航模试验也验证了压浪干舷的可行性和良好性能。

Abstract: A high-speed boat may encounter severe wave-making at the bow and become wetter at high speed. Some measures can be taken to overcome these disadvantages. In order to compare the effect of bow spray strips and Ω-type freeboards on a high-speed boat, hull wetness, resistance, hull motion, stability and the restoring moment of the heel at high speed of models with these two kinds of auxiliaries were calculated and measured. CFD methods and model tests were adopted. Both of these two auxiliaries can reduce hull wetness, and the model with a Ω-type freeboard has a better initial stability and larger restoring moment of the heel at high speed. A free running model test also indicates that the Ω-type freeboard has a fine performance.
