GARCIA-LEON, Ricardo Andrés. Thermal study in three vented brake discs, using the finite element analysis. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.200, pp.19-27. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v84n200.55663.

During the braking process, the heat produced by the friction between the brake pads and the disc is not quickly dissipated, this depends on the geometry and material of manufacture. Therefore, in the disc brake when a strong braking is caused, they can accumulate large amounts of heat in a short time, producing high temperature gradients. Under these conditions, functionality and safety of the brake system may be compromised. The objective of this research is to simulate the behavior of the temperature between the disk surface and the ventilation channels in three brakes ventilated disc, in order to compare the results obtained mathematically with those obtained in the Finite Element Analysis (F.E.A) with help Solidworks Simulation Software. The results show that the disks can be used effectively in extreme work conditions, while ensuring high levels of security. Given optimal performing maintenance and quality of the braking system.
