USING VIRTUAL ASSEMBLY TECHNOLOGY TO DESIGN AND DEVELOP THE ARJ21 BUSINESS JET BASE ON CATIA V5 AND ENOVIA VPM

摘要

Virtual Assembly is composed of a series of design activities. It is always covering assembly simulation, clearance analysis, assembly evaluation and information feedback, etc. But, this paper we place the emphasis on design process in VPM. At first, The basic technology of virtual assembly (DPD , CPD , VPM) is analyzed and the method of application of virtual assembly to aircraft design process is described in VPM environment.
