The Effects of Truck Structure Parameters on the Aerodynamic Drag and Optimization

Abstract:

The influence of different truck structure parameters on the aerodynamic drag is studied. Saving energy and reducing emissions are two worldwide issues. Decreasing aerodynamic drag for the truck becomes more and more important, which is investigated in this paper based on the CFD method. Three structure parameters of a real truck model are studied, including the height difference between the cab fairing and the trailer, the gap between the cab and the trailer, the angle at the bottom of the truck tail. Their impact on the flow field, pressure and drag are investigated. The results show that there is complicated nonlinear relationship between the structure parameter and the aerodynamic drag. A comprehensive optimization of those parameters can effectively reduce the aerodynamic drag. In this paper a 15% decrease of aerodynamic drag is observed by optimization.
