“…There are other ways to verify the simulated contact pressure. It could be estimated by using a pressure sensor film [58] without rotation of the disc or indirectly by estimating the real contact area and thereafter calculating the resulting contact pressure given the normal load. One way is to use a glass disc and record the evolution of the contact area with a camera, as done Eriksson et al [56] and Gramstadt [57].…”

The coefficient of friction (COF) is an important parameter when evaluating brake system performance. It is complex to predict friction due to its dependence on parameters, such as sliding velocity, contact pressure, temperature, and friction material mixtures. The aim of this work is to evaluate the macroscopic COF of a disc brake system under specific braking conditions by a meso-scale approach, using a cellular automaton simulation where the friction material mixture is modelled starting from its basic components. The influence of the local components in contact is taken into account. Simulated COF values are in line with the experimental values.

During braking, there is wear on both the rotor and the pads. This process generates particles that may become airborne. In fi eld tests, it is diffi cult to distinguish these particles from others in the surrounding environment. Therefore, a laboratory test stand has been designed which allows control of the cleanliness of the surrounding air. The test stand consists of a front right brake assembly mounted in a sealed chamber. A braking load is applied by a pneumatic system and the rotor, which has been pre-conditioned with a rust layer to simulate a car standing parked overnight in a wet environment, is driven by an electric motor. The number and size of airborne wear particles are then measured. This experimental set-up has been verifi ed by an initial test series performed at low braking loads. The results suggest that this test stand can be used to study rust layer removal from the rotor.
