In severe conditions, braking may cause the temperature on the disc-pad interface to rise up to 800 °C 1 . At such a temperature, the properties of organic compounds are disrupted, coefficient of friction (CoF) decreases, and the rate of wear increases exponentially. This phenomenon is called “fade” 2 . Ideal brake pads, without causing any fades, are expected to function in uniform and stable ...

Abstract Focusing strictly to the braking assembly system, it is an important key factor for safety, does not matter if can be found on cars, motorcycles, planes or bicycles. The principal aspect transform energies that act which are kinetic and potential, then leads a speed decrease of vehicle until stops. purpose this paper analyze five possible variants geometry brake disc, each being differ...

Substantially lightweight brake discs with high wear resistance are highly desirable in the automotive industry. This paper presents an investigation of precision-engineering design and development using nonhomogeneous Al/SiC metal-matrix-composite materials. The based on modeling analysis following stringent principles, i.e., brake-disc systems that operate repeatably stably over time as enabl...

Conventionally, Cast iron discs are used for brake discs. In the recent past, lightweight materials replace conventional in many vehicles to make them more fuel efficient. This work reports results of modelling and simulation using five different materials. AISI6150, Iron, Ti–6Al–4V, LM13 Al SiC MMC were considered as disc The temperature distribution, heat flux thermal gradient these analysed ...

An elastoviscoplastic three-dimensional model is proposed in order to predict the response of brake discs for a High Speed Train (T.G.V.), which are subjected simultaneously to mechanical and thermal loadings. This elastoviscoplastic law is based on the internal thermodynamic variables and takes into account the non-linear kinematic and isotropic hardening with plastic strain memory effect. A m...

The increasing demand from the consumer for higher levels of refinement from their passenger vehicles has put considerable pressure on the automotive industry to produce ever quieter cars. In order to prevent the occurrence of many forms of brake noise, especially judder and drone, excessive heating of the brake disc must be avoided, whilst minimising temperature variations across the rotor. In...
