Abstract: This study aims to propose a virtual space-based evaluation method for body in white skeleton size. This method obtains data from optical scanner and then splice in virtual space (PolyWorks), and uses the same evaluation method as physical fügen-meister bock (FMB) to quickly determine the part size. Thus replacing the traditional physical verification method of body-in-white Fügen-Meisterbock. This method not only improves the evaluation efficiency of body in white size, shorens the product development cycle and reduces the production cost, but also innovatively puts forward the whole life cycle monitoring scheme of data sealing management. Virtual Fügen matching technology is not only widely used in body-in-white manufacturing, but also provides a reference for the further research and application of virtual size evaluation of body in the future.
