Study Of Virtual Prototype Simulation And Modeling Techniques

With the support of virtual prototyping platform/environment, designers, users and manufacturers of the product can intuitively and visually improve the design, test the performance and use the virtual prototyping to simulate in the forepart of the product development. It has great significance in improving the design quality, decreasing the design faults and enlightening the designers.This paper first presents the basic concepts of virtual prototyping, then strongly lays emphasis on the workflow simulation which is the part of virtual prototyping, brings forward a object-oriented method of workflow modeling to develop a workflow modeling tool. The following section discusses NetMeeting-based technology of the virtual prototyping collaborative design and the redevelopment of NetMeeting in the collaborative simulation platform/environment. At the same time we probe into the integration of browsing and displaying the 3D models which are in the modeling database with the collaborative simulation platform. At last in the early design phase of product, we implement the primary integration of Expert System with the collaborative simulation platform/environment.
