Abstract
<div>In this article, an improved brake cooling simulation method is introduced. By
this method, the vehicle parameters, such as weight, height of the center of
gravity, wheelbase, and the like can be included to calculate the braking
thermal load under different operating conditions. The effect of the brake
kinetic energy regeneration (BKER) on the braking thermal load can also be
calculated by this method. The calculated braking thermal load is then input to
a coupled 3D simulation model to conduct flow and thermal simulation to
calculate brake disc temperature. It is demonstrated that by this simulation
method, the difference between the brake disc temperatures obtained from
simulation and vehicle test can be controlled below 5%.</div>
