Abstract: The clamshell style hood design of automobiles has become a highlight of automotive styling design due to its simple and novel appearance. The clamshell style hood has a large coverage area, and the side can extend downwards to the wheel arches. Compared with traditional hood, it increases the cost of parts and also affects the manufacturing process of sheet metal assemblies. The clamshell shaped hood of automobiles and its design advantages, analyzes the design factors that affect the manufacturing process, and discusses the influence of the was introduced and design angle of the A surface of the sheet metal shape and the joint position between the hood to the fender on the manufacturing process, a quantitative analysis method for product design improvement in the process of product synchronization engineering were discussed, which provides reference for the design and manufacturing of automotive clamshell hood.
