装载机工作装置CAD系统

THE CAD SYSTEM OF WORKING ATTACH- MENT ON SHOVEL LOADERS

本文论述了装载机工作装置CAD软件(Shovel Loader Working Attachment CAD System,简称SLWACADS)开发和研究的一般方法;提出了连杆机构动态模拟设计的方法;应用矩阵分析法建立了机构静力学分析系统;对循环分割法自适应网格生成技术进行了探讨,在此基础上建立了二维自动网格生成系统。 SLWACAD系统是一个对装载机工作装置进行设计和分析的专业软件,该系统是通过综合常规的设计方法和现代设计方法在微机上开发出来的。这个软件系统有一个良好的软、硬件集成环境,它充分地应用了软件工程和面向对象的程序设计(OOP)等现代设计技术,把设计、分析、计算和图形处理集成一体。整个系统包含了对工作装置的铲斗、动臂和连杆机构的设计、分析、计算和绘图等方面的多个功能模块,各功能模块之间既各自独立,又相互联系。功能块由中文选单和窗口控制,给用户提供了一个人机一体化的CAD系统。

This paper discusses the general method of the development and research for shovel loader working attachment CAD software, proposes the method of linkage dynamic simulation design, sets up the statics anlysis system by utilizing matrix analyt cal method, and researches into the automatic adaptive mesh generation techniques of the circle cut method. On the basis of these studies, we establish a two diminsion automatic mesh generation system. SLWACADS is a dedicated software system to the design and analysis of shovel loader working attachment. This system is developed in microcomputer by integrating regular design method and modern design methodology. This software system has a good software and hardware integrated enviroment. We fully apply modern design techniques of software engineering and orienced object programming (OOP), and combine design, analysis,calculate with graphics function. This system contains multi-function modules of design, analysis, calculation and drawing for shovel loader basket, boom and linkage, etc. Every function modules are controlled by Chinese menu and window. A man-machine interaction CAD system is provided for users.
