Virtual assembly of mechanical components and collision detection

Abstract

The application of advanced virtual reality technology and product exchange technology is the main process of the virtual prototype for supporting virtual assembly of product life cycle. Taking a typically complex mechanical product – pumps as an example, this paper analyzed the assembly model of mechanical products, built the virtual assembly scene, and applied the DFA and virtual reality technology to implement the virtual assembly, virtual operation and real-time interaction through VRML and Script nodes in the virtual environment. Meanwhile, by applying the method of Bounding Boxes, the collision detection analysis during the process of assembly is completed. It presented a new design and implementation method for developing complex machinery.
