STUDY ON THE BODY AERODYNAMICS IMPROVEMENTS OF THE ELECTRIC VEHICLE HaUI-EV2

Abstract

This paper reveals the research on the aerodynamics improvements caused
by the vehicle’s body shape of an electric vehicle HaUI-EV2. In reality, the drag
force calculation of a vehicle is very hard because the vehicle’s body is assembled
by many components that their drag coefficients are not the same. Therefore,
the electric vehicle’s body model is basically designed by SolidWorks software
and simulated by CFD tool in Ansys. To evaluate the quality aerodynamics of a
vehicle, the important factors such as the drag, lift force and air tube flow must
be concerned. The results of this article are the significant factor to design,
manufacture, experiment and optimization in order to enhance the the body
shape’s aerodynamics characteristic of the electric vehicle HaUI-EV2.
