摘　　要：在讨论虚拟装配技术内涵的基础上,提出基于VRML-Java的虚拟装配系统体系结构,该系统实现了装配模型与显示模型的分离,以及系统的平台无关性。分析了虚拟装配环境的构建方法,论述了产品装/拆运动的表示及变换、虚拟装配过程控制策略、虚拟装配中的碰撞检测方法,以及Java与VRML的通信等系统实施的关键技术。开发了虚拟装配仿真软件,以球阀为例进行了验证。A Virtual Assembly System（VAS） structure based on VRML-Java technology is presented. It makes assembly model and show model separate each other and its running is independent of computer platform. The constructing methods of VAS environment and key technique of VAS implementing are discussed. This key technique consists mostly of expression and transformation of assembly/disassembly motion, control strategies of virtual assembly process, collision detection among objects in VAS and communication between Java and VRML. The VAS simulation software is developed and validated by taking example for ball valve virtual assembly.
