虚拟现实仿真技术及在飞机装配中的应用

虚拟现实技术应用于仿真系统中,将极大地拓展仿真技术的研究和应用领域,具有广阔的理论及实际意义.利用目前先进的VRML(虚拟现实建模语言)进行三维环境构型的基础上,以Java语言设计仿真器并在三维环境下实时驱动对象进行运动,提出及完成了基于因特网浏览器的虚拟现实仿真技术方案,达到了虚拟现实仿真的基本要求,并以某飞机制造公司的波音737-700尾段的生产过程作为实际应用背景,进行了生产过程的可视化仿真及虚拟现实仿真的实证研究.

Virtual Reality Simulation and Its Application on Aircraft Assembling

The mechanism of virtual reality simulation is deeply discussed. By means of the popular VRML 3D constructing language to build virtual reality scene and objects, and Java general programming language to code the mobile engine, which not only can complete the normal numeric simulation but also drive the virtual reality objects running according to the simulation event logic, this simulation system is realized on normal computer without any extra hardware requirements and meets the fundamental interactive requirements of virtual reality system.This fundamental, practical but powerful virtual reality simulation system is mainly applied on world wide web, and can be easily installed in any Java integrated development environment and extended to more utilized fields. Furthermore, a virtual reality simulation model for the assembling process of Boeing 737 700 aircraft is researched and constructed by such theory and methods. Finally, the future development of this virtual reality simulation mechanism is also discussed to show the prospect.
