一个虚拟装配支持系统的实现

虚拟装配是虚拟制造的核心关键技术之一。为了实现产品的虚拟装配，自主开发了虚拟装配支持系统（VASS），它能够在虚拟状态下对产品装置进行分析、仿真，实施数字化预装配，生动直观地分析、验证与改善产品的可装配性。文章介绍了该系统的总体结构，讨论了主要关键技术，如装配模型、装配顺序规划、装拆运动表达、干涉检查等。该系统已在实际项目中得到有效应用。

Introduction of a Virtual Assembly Supported System

Virtual assembly is one of the key technology of virtual manufacture. A virtual assembly supported system (VASS) is developed for the application, with which a product can be analyzed, simulated and pre-assembled virtually, meanwhile its assemblability can be verified and improved dramatically. The structure of VASS and main key technology are introduced, including assembly modeling, sequence planning, the presentation of assembly\disassembly move, and interference checking. The system has been applied effectively to some engineering projects.
