【摘要】 螺旋桨是船用推进器中应用最广的一种。目前计算机辅助设计制造(CAD/CAM)已经在众多领域中得到了广泛应用。本文通过利用CAD/CAM技术在玻璃钢游艇设计开发平台中构建螺旋桨设计模块,来自动完成游艇用Ma螺旋桨的设计并生成三维模型。本文首先介绍了玻璃钢游艇与CAD/CAM技术的发展现状,分析了目前计算机在螺旋桨设计方面的应用情况。有别于常规图谱设计方法和回归设计方法,本文提出一种全新的基于螺旋桨敞水性征曲线上的图谱设计方案,并给出该方案的详细介绍。螺旋桨设计模块利用Visual C++语言程序进行编写,三维模型生成利用的是CAD软件Pro/ENGINNER,在本文当中给出了这两种工具的简要介绍。由于该模块构建在已有的玻璃钢游艇设计开发平台之上,文中给出平台的总体程序界面和流程图,以及各模块的功能介绍。接着对螺旋桨设计模块给出了详尽介绍:运用Visual C++编写程序实现前文中介绍的图谱设计方案,通过参数输入得到最佳螺旋桨设计结果,并生成桨叶叶切面型值表。常规的螺旋桨CAD绘图给出的是螺旋桨设计总图,而本文则是尝试通过编制Pro/TOOLKIT程序,调用Pro/ENGINNEER自动生成螺旋桨桨叶三维模型。该模块交互界面简单友好,实现可视化操作,经过实例校核,结果较为准确。生成的三维模型结合自动化技术可直接生成螺旋桨铸模,在实际生产中具有可行性。更多还原

【Abstract】 Propeller is a kind of watercraft’s thruster, which is used most widely. At present, CAD/CAM is being applied in many fields. This paper built the propeller design module on the platform of yacht design by using CAD/CAM technology. The module designs the Ma Propeller and builds the three-dimensional model automatically. At first, this paper introduced the present situation of yacht development, analyzed the application of computer in propeller design. Being different from general charts design and regression method, the paper put forward a brand-new charts design method and introduced the method detailedly. The propeller design module is built by Visual C++ and the 3-D model is built by Pro/ENGINNER, this paper gave the introduction of this two tools. Because the module is built on the presently platform of yacht design, this paper introduced the platform’s macroscopical interface, the flow chart of program and the functions of all the modules. In succession, the paper gave the particular introduction of the propeller design module which carries out the charts design method by compiling Visual C++ program, gets the design results of the prime propeller and creates the form of the section’s geometry parameters. The general propeller’s plot is the propeller’s collectivity drawing, but this paper is trying to build the 3-D model of the propeller using Pro/e by compiling the Pro/TOOKIT program.The module’s mutual interface is friendly and simply to operate,the design results is proved to be comparatively exact by checking the practical example. The 3-D plot of propeller can be used to creates the substantial propeller’s model by combining the automatization technology. It has the feasibility in the practical manufacture.更多还原
