基于MFC与OpenGL的可视化机械仿真设计系统

通用可视化机械设计系统对硬件要求高,其仿真运动模拟一般不响应定量数据输入.为此,本文研究了一种对硬件要求低且运动仿真模拟能实时响应定量数据输入的机械设计系统.该系统基于微软基础类库(MFC)与开放图形库(OpenGL)以及科学计算软件而开发.开发实例表明:相较于大型CAD软件,该系统具有更为快速的绘制功能,对于不同精度条件下的零件数据都能够计算并予以可视化显示.该设计系统能够实现机械零件的快速设计和开发.同时给出了对心尖顶直动从动件盘形凸轮机构可视化系统开发实例.

A Visual Mechanical Design System Based on MFC and OpenGL

The general visual mechanical design system is more demanding of hardware and the motion simulation generally does not respond to quantitative data input. In light of this, this paper researches on a mechanical design system that is not much demanding of hardware and can respond in real time to quantitative data input in motion simulations. The system is based on the Microsoft foundation Class Library （MFC） and the open Graphics Library （OpenGL） and computer software development. Development examples show： compared to large CAD software programs, the system is of a faster drawing function, and it is capable of calculating and visualizing component data under different conditions of precision. It can achieve rapid design and development of mechanical parts. The paper also gives an example of visualized system development of disc cam mechanisms.
