Description

船舶船艏
技术领域
本实用新型涉及一种船舶的船艏,特别是一种兼具球鼻型船艏和穿浪型船艏二者优点的船舶船艏。
背景技术
船舶是人们出行、运输等活动中一种重要的交通工具。随着人们对船舶航行和运输速度要求的提高,整体重量更轻、航速更快的船舶也越来越多的投入使用(如铝合金船舶),但是这些高速海洋船舶普遍存在船艏波激严重的现象,当船舶进入半滑行状态后,船艏破浪所引起的波浪飞溅很大,这种情况不仅加大了船舶的破波阻力,也对船舶的航行状态、航行舒适性产生不良的影响。因此现在需要一种能够解决上述问题的新型高速船舶。
发明内容
本实用新型是为了解决现有技术所存在的上述不足,提出一种结构巧妙,设计合理,兼具有球鼻型船艏与穿浪型船艏两种不同船艏优点的船舶船艏。
本实用新型的技术解决方案是:一种船舶船艏,其特征在于:所述的船艏的长度是整体船长的0.1-0.15倍,船艏的宽度为整体船宽的0.2-0.3倍,船艏的高度为船体型深的0.5-0.8倍,船艏在水平方向上断面的轮廓由两条轴对称的样条曲线组成,所述的样条曲线满足以下方程式:
Figure 292599DEST_PATH_IMAGE002
Figure 44654DEST_PATH_IMAGE003
,mj为待定常数,hj为步长,xj,yj为型值点。
本实用新型同现有技术相比,具有如下优点:
本种结构形式的船舶船艏,其结构简单,设计巧妙,它充分考虑到了船舶在高速航行状态下,尤其是进入半滑行状态后,造成较大的波浪飞溅后,破波阻力增大,同时考虑船舶此时航行的状态和舒适性也较差的情况,对船艏与船舶的整体比例做出具体限定,并且船艏在水平方向上的断面的轮廓线是由两个满足一具体方程式的样条曲线组成,这种轮廓的船艏较普通的球鼻船艏狭窄,又比穿浪型船艏更宽,因此它既具备了球鼻型船艏可以改善艏部流场,减小阻力的优点,又具备了穿浪型船艏在高速航行状态下保证船体稳定,降低兴波阻力的优点。因此可以说这种船舶船艏具备了多种优点,特别适合于在船舶制造、生产,海上航运等行业中推广应用,其市场前景十分广阔。
附图说明
图1是本实用新型实施例的水线图。
具体实施方式
下面将结合附图说明本实用新型的具体实施方式。如图1所示:一种船舶船艏,船舶船艏设置在船体的前端,船舶船艏的长度为整体船长的0.1-0.15倍,船艏的宽度为整体船宽的0.2-0.3倍,船艏的高度为船体型深的0.5-0.8倍,并且船艏在水平方向上断面轮廓是由两条相互轴对称的样条曲线组成,并且这个样条曲线满足以下方程式:
Figure 867117DEST_PATH_IMAGE004
Figure 71833DEST_PATH_IMAGE003
,mj为待定常数,hj为步长,xj,yj为型值点。
船舶设计人员在确定船舶船艏的具体结构时,根据上述方程式来获得具体样条曲线的形状,并根据其形状来加工、制造出船艏。采用这种的方式设计和制作而成的船舶船艏,相比于传统的球鼻船艏,体形更加狭窄,更加接近于穿浪型船艏,因此具备了更好的穿浪性能,改善兴波阻力;同时它相比于传统的穿浪型船艏,其体形又较为尖锐,更加接近于球鼻型船艏,可以提高船舶航行时的稳定性。
