Virtual prototype technology and its application in the design for car audio

The conception of Virtual Prototype technology are described,the Virtual Prototype's module and its function frame are given.As an example that the structural performance simulation and lighting test for the volume tuning and four direction choosing system,the way to built up expert system of analysis and evaluation development and integrated simulation frame about car audio based on virtual prototype technology is presented.With the help of CATIA software,three-dimensional model of light guide plate and their components is established.By the used of software ANSYS,which is an important CAE tool in the virtual prototype platform,strength analysis has been calculated,the physical properties of materials is selected form the platform' database.The ultimate result reveal,light guide plate and their components have been calculated to meet the strength requirement.At the same time,SPEOS CAAV5 software is used for light simulation for volume adjustment and four selection system,the results show that the design meets the illumination light gray and uniformity requirements.In the primary application practice,the system developed based on VP can effectively support the product development.
