Abstract:

Taking a simplified model of a home-made minibus that loas verified by tests as the object of study, the factors affecting its aerodynamic characteristics were numerically simulated. The aerodynamic drag and lift were calculated upon the changes of the angle of rear wind window, the angle of the back, and the upward omgle of underbody diffuser, and the relationships among these variables were obtained. The optimal styling achieved by their appropriate combination. The simulation results showed that the above-mentioned 3 angles make notable impact on the aerodynamic characteristics of the minibus, and it is necessary to combine them optimally by numerical simulation and test in the process of development. The obtained conclusions provide a theorezical foundation for the styling optimization and the new model development.

Key words: vehicle engineering, minibus, tail-end styling, numerical simulation, aerodynamic characteristics
