“…The study of sensitivity in disc-pad systems is now attracting the attention of research community (see e.g. [128,129,126,130,127]). In [131], to take the uncertainties into account, descriptive statistical analysis tools were used.…”

Disc brakes have evolved over time to be a reliable method of decelerating and stopping a vehicle. There have been different designs of disc brake systems for different applications. This review gives a detailed description of different geometries of the components and the materials used in a disc brake system. In spite of all the improvements, there are still many operational issues related to disc brakes that need to be understood in a greater detail and resolved. There has been a lot of research going on about these issues and at the same time different methods are being proposed to eliminate or reduce them. There has also been an intensive fundamental research going on about the evolution of tribological interface of disc-pad system. One major purpose of the present paper is to give a comprehensive overview of all such developments.

“…This article discusses the elementary solutions governing the antiplane, elastodynamic contact between two elastically similar bodies in the presence of friction and slip. Elastodynamic contact is of particular relevance at high strain rates [1], under shock [2,3] or ramp loading [4], and generally in the description of contact problems where the representative time and lengthscales are comparable to the relevant speeds of sound of the material, such as those that may for instance be encountered in turbine shaft bearings [5,6,7], where the loading rates quickly approach the material's speed of sound; in joints in flexible structures, where the speed of sound at the joint is much slower than that at the structure itself [8,9]; or in brakes, where dynamic contact is involved in frictional induced vibrations [10,11] which are also of relevance in structural mechanics [12,13,14]. In such situations, the conventional contact equations ought to account for the inertial forces of the material, and the problem, formerly parabolic, becomes time dependent and hyperbolic.…”

This article models the elastodynamic transient contact between two elastically similar half planes under antiplane loading and in the presence of friction. Contact is maintained along the positive real line under the presence of a certain remote contact pressure. An antiplane shear load is applied, which entails interfacial shear traction that opposes the frictional force entailed by the contact pressure. In order to balance the surface tractions, the surface must be allowed to slip. We derive the closed form solution of the interfacial traction due to a general antiplanar displacement distribution using a variant of the Wiener-Hopf technique. We also find closed-form expressions for the interfacial shear traction due to this remote antiplane load. In combination with the frictional force, this leads to an integral equation the solution to which is the distribution of relative slip. We quantify both this and the magnitude of the interfacial shear tractions under diverse loading, showing that transient loading leads to partial reverse slip of the contact surfaces. We show that the reverse slip tends to vanish over time, and that it is ameliorated if the friction coefficient is reduced.

“…It is known that the interfacial friction events are quite complex, and brake squealing may be excited when a rotating braking disc rubs against the brake pad under certain operating conditions. The squeal phenomenon is highly susceptible to both controlled and uncontrolled factors 3 of the brake system, such as the surface roughness and wear, 4–7 the inherent properties of the frictional materials, 8–11 thermal effects, 12–14 and the influence of added damping. 15–17 Much research work has been performed during the past few decades to identify and analyze the factors influencing squeal noise and their interaction mechanisms, both through experimental tests 5,18,19 and through numerical approaches.…”

In this study, a bespoke small-scale brake dynamometer was developed to simulate the braking conditions of a railway disc brake system. Braking squeal experiments were performed with this brake dynamometer at different braking pressures and disc rotation speeds, and the influence of these braking parameters on the generation and characterization of the squeal noise was evaluated and discussed. The obtained results show that both the braking pressure and the disc rotation speed have a significant influence on the generation and evolution of the squeal noise. Higher rotation speeds are found to result in higher sound pressures and more complicated squeal noise spectra, except at a particular braking pressure, for which the highest sound pressure level is found at various disc rotation speeds. This phenomenon indicates that a combination of specific braking parameters may lead to a strong instability of the brake system and consequently to squeal noise. Additionally, a possible correlation of the squeal noise characteristics with the pressure distribution at the braking interface was found and discussed.
