基于VR技术的虚拟维修仿真系统设计与应用

针对产品并行研发模式下的维修性问题，将虚拟现实技术引入到产品维修仿真中，即在计算机生成的虚拟现实环境中对产品进行维修仿真分析。文中以单通道被动立体投影系统为虚拟现实环境，以DELMIA、VRCO VisTool、CDVI、Pro/E等软件为虚拟现实软件系统，构建了一个虚拟维修系统，阐述了系统中VR外设集成、环境建模与数据转换、碰撞检测、人机工效和立体显示等关键技术。最后以某型雷达天线转台维修为例，验证了虚拟维修的有效性。

Design and Application of Virtual Maintenance Simulation SystemBased on Virtual Reality Technology

This paper focuses on the product maintainability. It introduces virtual reality technology to the product maintenance operation in the concurrent development mode. That is, maintenance simulation for product in computer-generated virtual reality environment. This paper establishes a virtual maintenance system using passive single three-dimensional protection system as virtual reality environment, employing DELMIA, VRCO VisTool, CDVI, Pro/E soft wares as virtual reality software system. Meantime, it illuminates VR peripheral integration, environmental modeling and data conversion, collision detection, human ergonomic, three-dimensional display and other key technologies. Finally, a sample is given on the validity of the virtual maintenance through certain radar rotating platform maintenance.
