Abstract
A hood structure comprises an outer and an inner which form a closed cross section through spaces. The inner's cross-sectional shape is a sine curve, an nth-power-raised sine curve, or a spline curve having a corrugation length approximate to an outside head diameter. This corrugated hood structure can provide a uniform, excellent head impact resistance independently of impact positions on the hood. The corrugated hood structure also excels in tension rigidity, bending rigidity, and torsional rigidity. Accordingly, the car body hood panel structure satisfies requirements of head impact resistances for pedestrian protection and rigidity improvement such as the tension rigidity.
