【摘要】：剪叉式液压升降平台行业发展迅速，在国内有众多的生产企业。剪叉式液压升降平台虽然已有国产化的自主品牌，但是其设计方法不尽完善，在产品开发方面，现代化设计方法的应用研究较国外落后很多，从而导致产品笨重，开发周期较长，传统的设计及分析方法越来越不能满足产品性能提高及资源的有效利用。本文通过对剪叉式液压升降平台进行分析计算，推导了决定剪叉式液压升降平台功能的各参数的理论解析式，在此基础上提出了可视化、参数化的CAD系统设计思想。在CAD系统的开发中，，利用VS2005的VC++语言模块对主流的Pro/ENGINEER三维设计软件进行二次开发，采用Pro/TOOLKIT同步模式（Synchronous Mode）进行设计。此过程是通过编译VS2005应用程序生成的接口文件，实现Pro/ENGINEER、Pro/TOOLKIT与MFC三者之间的数据通信，同时还利用Pro/TOOLKIT提供的UI对话框函数、菜单函数，并结合VS2005可视化界面技术和数据库技术设计出人机交互界面，实现了剪叉式液压升降平台零部件的参数化设计。主要研究内容如下： 1.通过分析剪叉式液压升降平台的结构特点，建立了一液压缸推动三幅剪叉臂的升降平台的数学模型，利用杆组分析的理论对各参数进行计算，推导出各个参数之间的关系及规律性。 2.以Pro/ENGINEER三维软件为平台建立剪叉式液压升降平台各零部件实体模型及装配模型，并进行数据库开发与组件的参数化研究。 3.以Pro/ENGINEER二次开发应用程序Pro/TOOLKIT为平台，利用VS2005集成开发环境实现菜单设计、对话框设计、MFC用户界面设计。编制了界面友好，功能齐全的人机交互环境。 4.利用Pro/MECHANICA模块的运动分析功能实现剪叉式液压升降平台的运动仿真。通过以上研究开发出一套完整的剪叉式液压升降平台CAD系统，系统界面友好，操作方便，功能强大，显著缩短了产品的设计周期，提高了设计水平，具有较强的实用价值和广阔的发展前景。
[Abstract]:The industry of shear-fork hydraulic lift platform develops rapidly, and there are many production enterprises in our country. Although the shear-fork hydraulic lift platform has its own domestic brand, its design method is not perfect. In product development, the application research of modern design method lags far behind that of foreign countries, which leads to heavy product. Because of the long development cycle, the traditional design and analysis methods can not meet the requirements of product performance improvement and efficient utilization of resources. Based on the analysis and calculation of the shear-fork hydraulic lifting platform, this paper deduces the theoretical analytical expressions of the parameters that determine the function of the shear-fork hydraulic lifting platform, and puts forward the visual and parameterized design idea of the CAD system on this basis. In the development of CAD system, the main Pro/ENGINEER 3D design software is redeveloped by using VC language module of VS2005, and the synchronous mode of Pro/TOOLKIT is used to design it. In this process, the interface file generated by VS2005 application is compiled to realize the data communication between Prop / engineer ProP / toolkit and MFC. At the same time, it also uses the UI dialog function and menu function provided by Pro/TOOLKIT. Combined with VS2005 visual interface technology and database technology, the man-machine interface is designed, and the parameterized design of the components of the shear-fork hydraulic lifting platform is realized. The main contents of the study are as follows: 1. By analyzing the structural characteristics of the shear-fork hydraulic lifting platform, the mathematical model of the lifting platform with three shear arms driven by a hydraulic cylinder is established, and the parameters are calculated by using the theory of rod group analysis. The relationship and regularity of each parameter are deduced. 2. The solid model and assembly model of the parts and components of the shear-fork hydraulic lift platform are established on the platform of Pro/ENGINEER, and the database development and the parameterized research of the components are carried out. 3. On the platform of Pro/ENGINEER secondary development application program Pro/TOOLKIT, the menu design is realized by using VS2005 integrated development environment, and the user interface design of dialog box is designed. A friendly interface and complete function man-machine interaction environment is developed. 4. The motion simulation of shear-fork hydraulic lifting platform is realized by using the motion analysis function of Pro/MECHANICA module. Through the above research, a complete CAD system of shear-fork hydraulic lifting platform is developed. The system has friendly interface, convenient operation and powerful function. It shortens the design cycle of the product and improves the design level. It has strong practical value and broad development prospect.
