| dc.description.abstract | En el sistema de frenado, el calor generado por la fricción entre el disco y la pastilla debe disiparse lo más rápido posible. En este trabajo se estudiaron cinco frenos de disco comunes en automoción mediante teorías matemáticas de transferencia de calor y métodos numéricos utilizando el software ANSYS. Además, se realizó una comparación directa entre los valores experimentales, teóricos y de simulación encontrados en la bibliografía abierta para proponer un freno de disco con una geometría mejorada en términos de disipación de la transferencia de calor. Se consideraron los resultados numéricos para proponer dos posibles soluciones de geometrías de frenos de disco utilizando álabes de ventilación N-38 utilizados en ingeniería aeronáutica. Se logró una mejora en la disipación de la temperatura de aproximadamente un 23,8 % en comparación con las cinco geometrías analizadas con una pala de ventilación simple de tipo N-38. La disipación del calor en los frenos depende en gran medida de la geometría del disco, la geometría de las palas, el material con el que está fabricado, el material de la pastilla, el peso del vehículo y las condiciones de funcionamiento, como se puede verificar con cálculos matemáticos y experimentos. Los resultados obtenidos demuestran que los discos pueden utilizarse eficazmente en condiciones de trabajo extremas (80 km/h y 33 °C), sin afectar a la seguridad de los ocupantes y al sistema de frenado. | en_US |

| dc.description.abstractenglish | In the braking system, the heat dissipation generated by the friction between the disc and pad should be evacuated as quickly as possible. In this work, five common different automotive disc brakes were studied through mathematical theories of heat transfer and numerical methods using the ANSYS software. In addition, a direct comparison between experimental, theoretical, and simulation values found in the open literature was performed to propose a disc brake with an improved geometry in terms of dissipation of heat transfer. The numerical results were considered to propose two possible solutions of disc brake geometries using N-38 ventilation blades used in aeronautic engineering. An improvement in temperature dissipation was achieved by approximately 23.8% compared to the five geometries analyzed with a simple type N-38 ventilation blade. The heat dissipation in the brakes strongly depends on the geometry of the disc, the geometry of the blades, the material from which it is manufactured, the material of the pad, the weight of the vehicle, and the operating conditions, as can be verified with mathematical calculations and experiments. The results obtained demonstrate that the discs can be used effectively in extreme working conditions (80 km/h and 33◦C), without affecting the safety of the occupants and the braking system. | en_US |
