@@@@In order to realize structure optimization and composited structural design, this paper presents composited steel and plastic body structure. It verified feasibility of this structure by sample parts, then built composited steel and plastic body structure on traditional sheet metal body, size optimization is also made. The optimization shows that, with the reduction of body gross mass of 51 kg, the composited steel and plastic body structure has improved to different extent in static and dynamic characteristic. Finally, engine hood assembly test proved advantages of lightweight of such body structure.
