文档介绍：山东理工大学硕士学位论文 Abstract
drag coefficient from two factors that are the lateral distance and installation position, as well as the influence of the number of holes in wheel spoke on the aerodynamic drag coefficient was analyzed, and the influence law on the external flow field was obtained.
As to how to select optimal shape parameters for car body design, a reasonable method was offered, which has a basic reference in the vehicle body modeling optimization.
Key words: Car body; Numerical simulation; Air drag coefficient; External flow field ; Orthogonal experiment
