Abstract: The parametric FE model of three-box type body is created. The development platform of auto body concept design is created according to the development process and the characteristic of auto body concept design, which included most analysis and optimization method of development and realized integration of three-box type body FE model and development platform. This make designers can control the process of concept design auto body under a unified operational condition. The research presents that, this system can carry out the integration of CAD/CAE in early auto body development, enhance the efficiency of project selected and the reliability of structure designed. It has good flexible and make design efficiency improve.
