Identification of the topographic variability of different brake pad morphologies
Although a great deal of progress has been made in recent years, reducing the noise emitted by braking systems is still a topical challenge for the scientific community and automotive manufacturers.
It is now recognized that the squeal phenomenon is related to a floating-type instability due to the non-conservative nature of friction, which can be demonstrated by studying mode coupling. Numerical simulations are often based on a nominal system model. However, braking systems are complex structures with considerable variability. For example, the nature and evolution of the topography of contact interfaces are significant parameters generally leading to different behaviors of brakes from the same production family.
.The aim of this project is to measure, analyze and represent the topography of brake pad contact surfaces using random fields. Four morphologies, from three OEMs, for three different braking systems are considered. Tribometer tests will also be carried out for all possible configurations on one of the braking systems. The aim of these tests is to assess the potential relationship between the different pad morphologies and the brake's propensity to squeal.
