THE ANALYSIS OF VIRTUAL ASSEMBLE USING VIRTUALREALITY TECHNIQUES IN HELICOPTER STRUCTURAL DESIGN

Virtual reality is a technology which is often regarded as a natural extension In 3D computer graphics with advanced input and output devices. This technology has only recently matured enough to warrant serious engineering applications. The integration of this new technology with software systems for engineering,design,and manufacturing will provide a new boost to the field of computer- aided engineering. One aspect of design and manufacturing which may be significantly affected by virtual reality is design for assembly. This paper presents a research effort aimed at creating a virtual assembly design environment in helicopter structural assembly.
