并联坐标测量机理论模型及其虚拟原型研究

Model Theory and Virtual Prototype of a Kind of CMM Using Parallel-link Mechanism

首先介绍了一种三自由度关联机构坐标测量机的结构、特点及工作原理 ,然后建立了该坐标测量机的测量模型 ,最后 ,在Windows98开发环境下 ,通过 VC++6 .0调用 Open GL 图形库中的图形函数 ,对该坐标测量机的虚拟原型进行了参数化三维建模与仿真 ,从而为真实样机的制作奠定了基础。

Firstly, this paper describes the structure, measuring theory and characteristics of 3\|DOF parallel\|link coordinate measuring machine (CMM).Then, the measuring model of it is established according to the theory of the spatial mechanics. Finally, the virtual prototype of the new CMM is studied by using the graphics functions in OpenGL graphics library based on Windows 98 and Visual C++6.0. This research lays the foundation for manufacturing the real prototype of the parallel\|link CMM.
