| Abstract: | Taking a type of Multi Purpose Vehicles (MPV) as the research object, the parametric numerical simulation is performed on an aerodynamic characteristics optimization model. Based on design of experiment method and optimization algorithm, compared with the base model, the drag factor of the final optimization model is reduced by 4.69%. In addition, the aerodynamic influence of rearview mirror on the aerodynamic characteristics of whole vehicle is studied on the basis of design of experiment method, and the optimization simulation results of rearview mirror indicate that the drag factor of whole vehicle is reduced by 1.04%. |
