【摘要】 随着大型万能H型钢轧机的广泛应用,市场对其的需求随之增大,轧机设计的工作量也越来越大。为了减少大量的重复设计工作,提高设计效率,本文通过研究大型万能H型钢轧机的功能和结构,采用VC++6.0在大型通用CAD软件Pro/E平台上开发轧机设计系统,其研究成果对轧机参数化设计具有重要的理论意义和实际应用价值。本文将二次开发工具Pro/TOOLKIT与VC++6.0相结合,对二次开发的方法及模型样板的参数化技术进行了研究。通过分析轧机零部件的功能及结构,在Pro/E环境下建立了三维参数化模型样板,实现了ADO类对ACCESS数据库的访问功能,并创建了全局数据库,为零部件结构设计与装配设计提供了数据支撑。利用Pro/Toolkit的强大功能,结合MFC设计了软件的人机交互界面,实现了用户定义菜单的加载,完成了软件的集成。利用MFC和Pro/Toolkit提供的函数和变量,在基于数据库的基础上研究了轧机三维模型自动装配的问题,提出了在骨架基础上基于约束的自动装配方法。采用ANSYS软件机架进行有限元分析,并通过BP神经网络、带精英策略的非支配排序的遗传算法,对机架进行了圆角的多目标优化。在理论研究的基础上,开发了适用于轧机的参数化设计系统。能够实现轧机的三维设计,实现三维模型的生成,并进行轧机非标件的自动装配。本文提供了该系统的运行实例。
【Abstract】 With extensive application of the H-Beam universal rolling mill, the market’srequirement for quantity and species of the H-Beam universal rolling mill is increasing, sothe design work is gradually harder. In order to reduce abundant repetitive work, increasedesign efficiency, shorten the cycle from design to production, in this paper, the variantdesign system of the H-Beam universal rolling mill assembly model was established onthe panel of CAD software Pro/E by using VC++6.0, through the research about thefunction and construction of the H-Beam universal rolling mill, which have importanttheoretical meaning and practical application value for the digital design of H-Beamuniversal rolling mill.In this paper, the development environment of Pro/E software was introduced, whichwas combined by the redevelopment tool Pro/TOOLKIT and the VC++6.0. The method ofredevelopment and the parametric technique of the model template were studied. Based onthe function and construction of the H-Beam universal rolling mill, the3-D models werebuilt, in which the parameters were created. And the standard database was established, byusing family tables. The paper studied the method of manipulating the ACCESS databaseby using ADO classes. Then, the model data, model and the standard parts parameterswere added to datasheets, which indicated that the global database was finished. Theinterface of the software was designed by combining the features of Pro/Toolkit with MFC.The loading of user-defined menus was realized and software’s integration was completed.By using the functions and variables provided by MFC and Pro/Toolkit,the assemblingAutomation model of mill was studied based on the database.An automatic assemblymethod was proposed based on skeleton and restraint. The author analyzes model of theframe with finite element software ANSYS andoptimizes the round angle with multipleobject optimization method through the BP neural network and improved geneticalgorithm.On the basis of theoretical research, the parametric system of rollers is developed. It could accomplish the3-D design of rollers, then generate the model. This paper also givesan example of the application of this system.
