“…The study of high-frequency brake noise (brake squeal [400]), as well as low-frequency brake noise (creep-groan [401][402][403]), have resulted in some metrics and a test procedure for the multifunctional tribometer to assess brake friction materials concerning those brake noises.…”

“…Given that brake noise is strongly influenced by the geometry and detailed design of the mechanical system [14,17], the accelerometer measurements performed in the current investigation cannot be understood as the real noise generated in a car brake. Actually, when it comes of brake noise and vibration, technical literature [5,17,20] has raised many difficulties for reproducing the vehicle results in a sub-scaled testing machine. On the other hand, it is a common practice among brake materials' manufacturers to perform laboratory tests aiming to identify the propensity of friction materials to generate brake noise.…”

“…More than merely stop the vehicle, nowadays brake systems have numerous performance and quality requirements. As examples of those requirements, technical literature [1,17,23] has reported a reduced wear rate, steady coefficient of friction under a wide range of conditions and low level of noise and vibration. In the last 3 decades, special attention has been spent with respect to the last characteristic (brake noise and vibration), which has been considered more as a quality (or acoustic comfort) issue rather than performance issue.…”

“…However, the experimental observations are not always aligned with the consideration above, particularly in the unsteady environmental conditions such as the oscillations in relative velocity. Therefore, some engineering investigations have revealed that the frictional dynamics can be multi-valued, which means the friction force travels along different paths during the DS and the AS, and forms a non-reversible curve as reported in (Becker and Mahin, 2013;Biswas and Chatterjee, 2014;Neis et al, 2011;Outirba and Hendrick, 2014;Stefański et al, 2006;Wojewoda et al, 2008). The main reason for this phenomenon is the temporal lag between the variations of the friction force and the relative velocity.…”
