虚拟装配环境体系结构的建模机制与分析设计

虚拟现实技术为产品开发带来了全新的人机界面和强大的功能,虚拟环境将虚拟现实技术与产品的设计、装配和分析紧密地结合在一起。但目前大多数面向产品开发的虚拟环境存在着通用性和可重用性等问题。本文给出了一个虚拟装配环境软件体系结构,该体系结构基于统一建模语言UML和离散事件系统形式化描述体系DEVS思想,采用面向对象、可重用技术对该系统进行了分析设计,实现了软件体系结构的可扩展性、可重用性和易维护性等。

Modeling Mechanism and Design of Virtual Assembly Environment Architecture

Virtual reality brings the new interface and powerful function to the product development, and virtualenvironment closely connects the virtual reality with the design, assembly and analysis of the product. At present, however, most virtual environments oriented to product development have some disadvantages such as versatility and reusabilityThis paper gives architecture of virtual assembly environment, which is based upon the ideology of UML (United Modeling Language) and DEVS (discrete event system specification), and is designed using object-oriented andreusability technique. So, this architecture can implement the expansibility, reusability and maintainability of the virtual assembly environment system.
