Effect of Automotive Headlamp Modeling on Automotive Aerodynamic Drag
Automotive headlamp design, combining science with art, is essential in automotive modeling design. Headlamp modeling design should consider harmonizing with automotive modeling design as well as meeting the national standards of structural design and lighting property. The research aims to present an approach for headlamp modeling design considering automotive aerodynamic drag. The effect of different headlamp modeling design on aerodynamic drag and accordingly three sorts of parameters of headlamp modeling design combining with aesthetic demand are studied. An analytic model of headlamp on automotive aerodynamic drag is established. Numerical simulation of 3-D flow field around the automobile with CFD software is performed. The change of drag coefficient with parameters is analyzed. Finally the design rules of headlamp aerodynamic modeling optimization are concluded. The research effort will enrich the design means of automotive modeling and automotive headlamp, so as to improve the technical property.
