Abstract:
In order to improve the heat dissipation performance of the brake disc and reduce the air drag coefficient of the vehicle, the influence mechanism of the front wheel air dam and brake cooling guide structure is studied. Firstly, according to the flow field around the front wheel, six feasible air dam and guide flow optimization solutions are designed; then, CFD simulation method is used to simulate the flow rate, heat transfer coefficient and cooling time; secondly, for the air drag coefficient and brake cooling time of the whole vehicle, aerodynamic-acoustic wind tunnel and road test are used to test and verify respectively; finally, we get the solution of small front wheel air dam and open a guide flow channel around the plate (solution 4), the air drag coefficient is only increased by 3ct, and the brake cooling performance is much better.
