A Modeling Method of the Body of Conceptual Design Phase and the Application of Which In Pure Electric Car

A method of modeling method of the body using the simple structure surface is proposed. The structure surface model of half-integral pure electric car body is built. By transfer path analysis, it is known that structure surfaces are balanced in the bearing force, force transfer is consecutive, and the structure surface model is integrated. In addition, four force matrix equations respectively in the bending condition and in the torsional condition are derived, which are the basis of computing the simplified structure surface model.
