摘要小型高速滑行艇因机动性、强巡航速度高等优点得到了广泛应用。但是传统的单 体高速艇尽管巡航速度比普通排水船高，适航性能却有所欠缺，这样高速艇的发展就 受到了很大的限制。所以本文希望能找到一种在水面高速航行时能保持其拥有较大升 力系数和较小的阻力系数等从而能减轻船舶的颠簸现象的翼滑艇艇型。然而，目前来 说，高速艇的水动力性能方面的研究是一个难点。现有的相关研究基本都是依靠建模 实验来获得突破。我们先通过 Maxsurf 建立滑行艇的模型，再导入 Solidworks 中给船 舶加上水翼并建立船舶的三维模型，最后利用 Fine Marine 软件计算出船舶的水动力 性能。

由于国内外对于 H 型，M 型和燕尾型翼滑艇的研究有限，本文只能参考有限的 翼滑艇资料来进行船舶的三维建模以及后续的数值模拟计算和分析，我用 Fine Marine 软件上对这三种剖面的翼滑艇设定不同的航行速度，对其阻力，升力，船底压力以及 流场分布进行分析。先用 Maxsurf 软件建立不同剖面的翼滑艇的模型，分别是 H 型、 M 型和燕尾型。再将这三种模型导入 Cartia 进行船型表面的修复以及三维建模。最后 导入 Soliworks，用 FineMarine 对模型进行网格的划分，控制域的设定以及边界条件 的设定等等。然后利用 SST k-ε湍流模型来计算 H 型，M 型和燕尾型这三种翼滑艇在 不同速度下的水动力性能，阻力，升力，船底压力以及船舶周围流场的分布情况，并 将计算的结果进行对比分析。77326

本文通过各种软件的结合从而得出在一定速度下相对优良的剖面形式的船型，这 对翼滑艇水动力性能的进一步研究提供了一定的理论上的支持，以后通过软件模拟得 到较复杂的实验结果的方法会越来越普及，本文的研究方法和内容对未来对水翼艇的 研究提供了合适的数值计算模型，为未来的研究做好了铺垫。

Abstract Small high-speed gliders have been widely used because of the  strong maneuverability and high-speed cruising,such as coastguard cutter,high speed vessel,patrol boat and so on。While traditional single high-speed boat`s cruising speed is higher than ordinary drainage vessel, it is lack of seakeeping performance。It's for the applicability  of the high-speed craft, especially in the military on the use of development is limited by a lot。So this essay hopes to find a way to maintain larger lift coefficient, smaller resistance coefficient, drag lift ratio and static displacement in order to reduce turbulence phenomena of the ship。 However, the hydrodynamic performance of high-speed boat research is a difficult problem, it is basically solved through modeling experiment。Firstly, we establish the glider model through Maxsurf, then add hydrofoil to ship by importing it into Cartia and set up a 3d model。Lastly,we use Fine Marine software to calculate the hydrodynamic performance of the ship。

Because research for H, M and dovetail type is limited both at home and abroad, this essay only refers to limited data for 3d modeling of the ship and subsequent numerical simulation calculation and analysis。We analyse the drag, lift, bottom pressure  and flow field distribution of glider`s three sectionsat different speeds on Soliworks。Firstly,we establish H, M type and dovetail section of wing rowing model by Maxsurf software。Then we import the model to Cartia to repair the surface and make a 3d model。Lastly,we import the 3d model to Soliworks,and we use Fine Marine to pide grid,set the control field and set boundary conditions。 SST k -ε epsilon turbulence model is used to calculate the drag,lift,the distribution of pressure and flow field of bottom of the H, M rowing and dovetail wings of hydrodynamic performance under different speed 。 We analyse each ship calculation result to get the good ship type。 Soliworks11.8米玻璃钢翼滑艇艇型设计:http://www.youerw.com/jixie/lunwen_88873.html
