| Abstract: | Simulation analysis of the aerodynamics for a heavy truck was introduced in this paper by using the digital sim- ulation method. In the simulation,the drag coefficient and pressure of convective were obtained, and the key parts that maybe affect the drag coefficient were found. Further analysis inferred that it is better than before by optimizing the air deflector, and the drag coefficient can be reduced much more. |
