Abstract: A parametric FE（finite element） model for a sedan car is created in terms of the common structural features of cars. Also, autobody conceptual development platform is set up according to the procedure and the specification in autobody conceptual design, which includes main modules and methods for analysis and optimisation. Information integration between design platform and autobody parametric FE model is realised, and project management and the concept design process can easily be used within the integrated environment. The system fulfils CAD/CAE integration and optimisation for a structural scheme at initial design stage (conceptual design), and, consequently, increases efficiency and reliability for autobody structural design.

Key words: 〗parameterized design, conceptual design, auto-body development, finite element, information integration
