【摘要】：随着计算机技术的发展，计算机数控加工（CNC）、流体动力学分析（CFD）、有限元分析等现代化制造和分析技术在泵行业的应用越来越广泛。但作为上述技术重要链接点的叶片三维造型软件的开发还很不成熟。目前我国研发的商用绘图软件主要停留在二维CAD基础上，这种方法生成的几何图形并不能直接用于现代化制造和分析技术，造成了CAD和CNC、CFD、CAM的脱节，，导致工作效率低、产品研发成本高、企业竞争力下降等，严重阻碍了我国泵行业的发展。因此开发专用于泵产品的三维造型软件尤为重要。本文以曲面造型优越的三维软件UG NX6.0作为支撑软件，开发了一套设计离心泵叶轮、叶片、叶轮水力模型的三维造型软件。主要研究工作和成果有： 1、通过对UG二次开发工具和开发方法的分析比较，确定应用Visual C++6.0集成环境进行程序编译，选择适合离心泵叶轮三维造型软件开发的UG/Open API、UG/Open MenuScript和MFC联合开发方法； 2、应用Visual C++6.0集成环境中的MFC开发符合设计要求的非模式对话框，完成软件的人机交互界面设计，实现设计参数的输入、输出和数据的传递； 3、根据离心泵一元设计理论，结合软件开发方法，完成叶轮主要几何尺寸计算模块、轴面投影图绘制模块、流线分点模块、展开流线绘制模块、空间流线绘制模块、实体模型绘制模块的设计，并应用参数化和API函数，实现叶片、叶轮、叶轮水力模型的绘制。
[Abstract]:With the development of computer technology, The modern manufacturing and analysis techniques, such as computer numerical control machining, fluid dynamics analysis, finite element analysis and so on, are more and more widely used in pump industry. However, the development of blade 3D modeling software, which is an important link point of the above mentioned technology, is still far from mature. At present, the commercial drawing software developed in our country mainly stays on the basis of two-dimensional CAD. The geometry generated by this method can not be directly used in modern manufacturing and analysis technology, which results in the disconnection between CAD and CFD-CAM, resulting in low working efficiency. The high cost of product research and development and the decline of enterprise competitiveness seriously hinder the development of pump industry in China, so it is particularly important to develop 3D modeling software for pump products. In this paper, a 3D modeling software of centrifugal pump impeller, blade and impeller is developed with UG NX6.0 as the supporting software. The main research work and results are as follows:. 1. Through the analysis and comparison of UG secondary development tools and development methods, it is determined that the Visual C 6.0 integrated environment is used to compile the program, and the UG/Open API UG / Open MenuScript and MFC joint development method, which is suitable for the development of 3D modeling software for centrifugal pump impeller, is selected. 2. Using MFC in Visual C 6.0 integrated environment to develop the non-mode dialog box which meets the design requirements, complete the human-computer interface design of the software, and realize the input, output and data transfer of the design parameters; 3. According to the design theory of centrifugal pump and software development method, the main geometry dimension calculation module, axial projection drawing module, streamline dividing point module, developing streamline drawing module and space streamline drawing module are completed. The design of solid model drawing module, and the application of parameterization and API function to realize the hydraulic model drawing of blade, impeller and impeller.
