dc.description.abstractEste trabajo matemático experimental tiene como objetivo analizar los resultados obtenidos a partir de la transferencia de calor de un freno de disco típico de automoción y, así, comparar el comportamiento de la disipación de calor de este elemento mecánico en diferentes condiciones de funcionamiento. Los resultados demuestran que los frenos de disco pueden utilizarse eficazmente en condiciones de funcionamiento severas, con una velocidad de 36 km/h y una temperatura ambiente de 25 °C, sin afectar a la seguridad de los ocupantes ni al sistema de frenado. El uso de pastillas semimetálicas aumenta la temperatura sobre la pista de desgaste en torno a un 20 % más que las pastillas de amianto, pero la eliminación de material durante el deslizamiento es aproximadamente 2,5 veces mayor en las pastillas de amianto debido al acoplamiento en el sistema tribológico (pastilla y disco de freno). La disipación del calor en los frenos de disco depende de la geometría del disco, el material con el que está fabricado, el material de la pastilla, el peso del vehículo y las condiciones de funcionamiento, como se pudo verificar con los resultados matemáticos y experimentales, validando así la contribución de la eficacia del proceso de frenado durante su funcionamiento real.en_US

dc.description.abstractenglishThis experimental mathematical work aims to analyse the results obtained from the heat transfer of a typical automotive disc brake and thus compare the behaviour of heat dissipation of this mechanical element under different operating conditions. The results demonstrate that the disc brakes can be used effectively in severe operational conditions with a speed of 36 km/h and an ambient temperature of 25°C, without affecting the safety of the occupants or the braking system. The use of semi-metallic pads increases the temperature over the wear track superficial temperature by around 20% more than the asbestos pad, but the material removal during sliding is around ~2.5 times more for the asbestos pad due to the coupling in the tribosystem (pad and disc brake). The heat dissipation in the disc brakes depends on the geometry of the disc, the material from which it is manufactured, the material of the pad, the weight of the vehicle, and the operating conditions, as it could be verified with the mathematical and experimental results, thus validating the contribution of the effectiveness of the braking process during its real operation.en_US
