拖拉机前驱动桥虚拟装配应用研究

摘要

在分析和总结了虚拟装配技术研究现状的基础上,阐述了其原理,实施步骤以及关键技术的应用,并以拖拉机前驱动桥为虚拟装配对象,在计算机虚拟装配环境(Division Mockup)中装配并进行相应的装配检验,介绍生成装配序列与装配路径,并制作成装配动画的步骤,形象地展现产品的装配全过程.在(Division Mockup)中,以第三方插件为桥梁,借助由数据手套、位置跟踪器(FOB)、偏振眼镜和投影系统组建的虚拟现实环境,可以实现入机交互操作,并介绍了人机交互接口定义的规则和方法.%This paper analyzes and summarizes the current status of the virtual assembly technology research and elaborates its principle and implementing process. By taking the tractor's front drive axle as an object, a virtual assembly and its corresponding inspection is conducted in the computer virtual environment (Division Mockup). The generation assembly orders and routes are introduced. The procedure of assembly animation is set up to vividly exhibit the whole process of product assembly. By virtue of the third-party plug-in units and the virtual reality environment consisting of data gloves, polarization glasses, projection system, and position tracker (FOB), human-computer interaction can be achieved in Division Mockup. The rules and methods of human-computer interaction interface definitions are introduced as well.
