摘要：

An optimization scheme combining wind tunnel test and the design of experiment is adopted to optimize the aerodynamic performance of a MPV by multi-parameter optimization on rear spoiler itself and side trim panel. By optimization through wind tunnel test, the aerodynamically optimum styling scheme of rear end is obtained, leading to a drag reduction of around 2.9%. Then, a CFD simulation is conducted on the styling schemes both before and after optimization, their differences of tail-flow field and pressure distribution are compared and the cause of drag reduction is analyzed. Finally, the contributions of each region and part to drag change are compared, which further verifies the reason of drag reduction, providing the orientation of optimization for the aerodynamic development of the rear-end of MPV. © 2020, Society of Automotive Engineers of China.
