摘要
介绍了基于OpenGL的并联机床实体建模和运动仿真技术。对一种新型五自由度并联机床的机构特点进行了简单描述,并建立了机床运动的数学模型。利用OpenGL的图形库和矩阵堆栈建立了该机床整体结构的实体模型,利用坐标变换对机床进行了运动仿真,对机床进行了干涉检验,分析了运动仿真的实时性策略,并开发了并联机床的仿真系统。对于同一轨迹运动分别进行轨迹绘制,仿真系统用时12秒,机床样机用时10·8秒,二者结果基本一致。
The solid modeling and kinematic simulation method for Parallel Machine Tool（PMT） based on OpenGL are studied. The mechanism characteristics of a novel 5-DOF PMT are proposed and the kinematic algorithm of the PMT is presented. By using graphical library and matrix stack of OpenGL, the solid modeling of the whole machine tool is constructed. The kinematic simulation is realized by using matrix transformation. The interference checkout for the PMT is performed. The real-time strategy of the simulation is analyzed and the simulation software system for the PMT is developed. For drawing the same path, the rtmtime in simulation software system and the prototype of the PMT are separately 12 seconds and 10.8 seconds. The moving effects of the two ways are similar.
