Study on Virtual Maintenance Key Technology of a Certain Type of Equipment Based on Quest3D

当前用于开发复杂装备虚拟维修系统的平台主要有EON、Vega等,然而这些平台存在编程复杂、应用面少、价格昂贵等缺点。经过深入研究,本文解决了一系列关键问题,在Quest3D平台上成功地开发出了某装备虚拟维修系统,该系统对运行设备硬件要求低、逼真度高、开发及使用成本小。本文综合运用模型简化与优化技术实现了模型量大幅压缩的问题;提出了一种拆装序列智能生成的方法,实现了拆装序列的智能化生成;提出了光线阻挡算法与简单包围盒算法相结合的光线阻挡碰撞算法,实现了精确碰撞但又不影响系统运行速度。

Currently,to develop a maintenance system for complex equipment mainly depend on EON,Vega,etc,However,these platforms have shortcomings such as complex programming,small application areas,expensive and so on.After deeply researches,this paper solved a number of key problems,and successfully developed a virtual maintenance system for the equipment on Quest3D platform.The system has the advantages about low system hardware requirements,high fidelity,and low cost of development and use.This paper combined model simplification with optimization technology to achieve a substantial compression of the model amount;presented an intelligent method for the disassembly sequence generating;and by combining the light blocking algorithm with a simple？box-based algorithms,presented a collision ray check algorithm witch achieved precise collision without affecting system operating speed.
