Automatic Shape Optimization of Hatchback to Reduce Aerodynamic Drag

Abstract:

Taking a hatchback car as the research object to optimize its aerodynamic performance on styling stage, this paper was devoted to improve the efficient of optimization and reduce the blindness in aerodynamic drag reduction and optimization. By applying morphing software, optimization software, and fluid analysis software, an automatic optimizing process was developed, which could optimize different variables and levels at the same time even when there are no people involved, and finally bring up the best drag reduction scheme in combination.

Key words:styling stage; aerodynamic drag reduction; automatic optimization process
