高耐波性舰船船型设计研究

发布时间：2023-04-28 19:41

　　众所周知,深V船型具有高航速和良好的耐波性能。在过去的十年中,深V船型吸引起了美国,英国,中国等诸多国家对其的研究。现在,世界上许多国家都刚刚开始发展建造深V船型的军舰。一些专家指出深V船型单体舰艇将是未来发展的主流。在这样的背景情况下,对深V船型设计的研究开发对未来海军舰艇的发展是至关重要的。深V船型舰船的耐波性与其主尺度,V形斜升角,折角线高度相关。本研究的目标是对4000至5000吨的深V船型驱逐舰船体外形结构进行概念设计,进一步分析影响稳性,阻力和耐波性能数值结果的主因素。最后,提出优化方案,给出修改和优化后的驱逐舰船型。 船型几何参数对决定船体耐波性能的好坏有着重要作用。设计师的问题之一是选择哪些参数需要改变且参数改变多少才能达到最好的效果。往往一个参数的变化也会影响到其他参数。因此,本文给出的方案描述了在初步设计阶段,如何修改船型从而得到高耐波性能的船型的方法。为了确定船体参数和耐波性能之间的关系,通过改变折角线和修改其他的变量来系统的分析深V船型。使用MAXSURF计算机软件对船体进行了修改和耐波性能的计算。使用垂直加速度,横向加速度,横摇和纵摇标准对变量进行了评估。通过...
