【 摘 要 】

This research investigated the design of aerodynamic accessories of trucks using two methods. The first method designed accessories by computational fluid dynamics (CFD) to investigate the drag coefficient (CD). Case (a) was an unmodified truck which was used to compare with other cases. These cases were (b) addition of a bottom deflector, (c) addition of a roof deflector, (d) addition of a cover-gap and (e) addition of a closed-box. In case (a), the drag coefficient values decreases were0.04, 0.08, 0.11 and 0.14 respectively. In the second method, real aerodynamic devices were constructed, setup, and tested to investigate fuel consumption. In case (a) the fuel consumption decreases were 1.40, 2.00, 3.60 and 4.60 Liters/100 km respectively. The results show that the drag coefficients and the fuel consumptions correspond together. It confirms that computational fluid dynamics can be conducted to accurately design aerodynamic accessories of trucks and can be applied to the design of other accessories in the future.
