This paper presents an enhanced numerical–experimental framework for investigating the
dynamic instabilities of a pin–disk system, explicitly accounting for uncertainties at the frictional interface.
The main objective is to identify the key parameters that promote the onset of brake squeal on
simplified pin on disk system. On the numerical side, the approach combines the quantification and modelling
of geometric and material uncertainties, the construction of a modal database via clustering-based
modal tracking, and the propagation of uncertainties using data-driven metamodeling. Finally, a multiparametric
analysis of the evolution of the contact parameters is performed to characterise mode coupling
mechanisms.
