Abstract

The purpose of this paper is to design and build a brake booth in order to test the heating of a ventilated disc compared to an unventilated disc and their behavior in simulated, optimal conditions. The construction of the stand required the completion of stages such as the design of the brake stand, its actual construction, the diagnosis of the braking system, the behavior of the ventilated / unventilated disc in simulated conditions, the interpretation of the results obtained as a result of tests. The analysis was performed after comparing the temperatures developed at the level of the discs in the case of actuating the brake pads with different friction materials. The ARDUINO UNO R3 temperature module was calibrated using a container of water and ice, as well as an Optris PI 160 thermal imaging camera. The sensor was mounted on the disk and the ARDUINO UNO R3 module was connected to a laptop. In the first case, ordinary plates were used for both the ventilated and the unventilated disc. For the second test, wood was used as a friction material. For this, the plates were cleaned to the iron and then a piece of wood was glued with a thickness equal to the thickness of the material that was removed from the plate. An adhesive was used to stick the plate to the wood, after which it was pressed into a vise. The third test was performed with another material, namely aluminum. It has been found that regardless of the friction material used on the brake pads, the ventilated disc heats up more than the unventilated one. The cooling of the two discs was analyzed so that, for the ventilated disc, the temperature decreased from 38.61 ℃ to 25.15 ℃ in 48 [s], is by 13.46 ℃ while the unventilated disc temperature decreased from 38.55 ℃ to 33.93 ℃, cooling only by 4.62 ℃ in 48 [s].
