摘要

   进入21世纪,随着陆地上资源的开发,使陆地上的资源日渐枯竭,各能源消耗大国将开发目标转移到广袤的海洋。随着各沿海国家对海洋资源的深入开发,水下潜器成为不可缺少的重要工具。水下潜器的用途广泛,设计形式多样,即使同一用途的水下潜器,其结构类型也各不相同。在水下潜器的初步设计阶段,需要对水下潜器的阻力性能进行计算,从而为水下潜器配置合适的动力装置提供依据。水下潜器的节能问题十分重要,对于初步设计的水下潜器,在满足使用要求的前提下,对其外形进行阻力性能优化,减小潜器在水下受到的阻力,从而节省能源。

为了能估算水下潜器所受的阻力,首先参考有关书籍手工计算潜器的阻力,然后用 STAR—CCM+软件进行计算,从两方面各自计算,对结果进行比较,既可以得到较准确的结果,也可以对两种计算阻力的方法进行评价。在原型潜器的基础上改变其型线,生成后锥形潜器和平头潜器,并对其进行阻力计算。

本文以1m潜器为研究对象,结合相关阻力公式,利用 STAR—CCM+软件对其进行阻力计算及分析。

本文的研究包括以下的内容:

  (1)水下潜器的发展现状及其应用、 STAR—CCM+相关软件的概述及运用;

   (2)水下潜器的阻力特点及阻力计算方法;

   (3)利用 STAR—CCM+软件对1m潜器进行网格划分及运行该软件对其进行总阻力的计算;

  (4)参考相关书籍及公式对潜器阻力进行手工计算;

  (5)对比手工计算结果和软件计算结果,分析得出结论;

(6)计算后锥形潜器和平头潜器的阻力。

Abstract

     Into the 21st century, with the development of land resources, so that the resources on the land gradually depleted, the energy consumption of large countries will be the development goals transferred to the vast ocean. With the deep development of marine resources by coastal countries, underwater vehicles become an indispensable and important tool. Underwater submersible use of a wide range of design in various forms, even if the same use of underwater devices, the structure type is also different. In the initial design stage of the underwater vehicle, the resistance performance of the underwater vehicle needs to be calculated to provide the basis for the allocation of the appropriate power plant for the underwater vehicle. The energy saving problem of underwater vehicles is very important. For the preliminary design of underwater vehicles, under the premise of satisfying the requirements, the resistance performance of the submersible is improved, and the resistance of the submersible underwater is reduced, thus saving energy.

  In order to estimate the resistance of the submersible, the first reference to the books on the manual calculation of the resistance of the submersible, and then use STAR-CCm + software to calculate, calculated from the two aspects of the results of comparison, both can get more accurate results , Two methods of calculating resistance can also be evaluated.

  In this paper, 1m submersible as the research object, combined with the relevant resistance formula, the use of STAR-CCm + software to calculate and analyze the resistance.

   The study of this paper includes the following:

     (1) the status quo and application of underwater submersible, STAR-CCm + related software overview and application;

     (2) resistance characteristics of underwater vehicles and resistance calculation method;

     (3) using the STAR-CCm + software on the 1m submersible grid and run the software to calculate the total resistance;
