A unified approach for squeal instability analysis of disc brakes with two types of random-fuzzy uncertainties
TL;DR: In this article, a unified approach is proposed for squeal instability analysis of disc brakes with two types of random-fuzzy uncertainties, i.e., the random and fuzzy model, in which random variables and fuzzy variables exist simultaneously and independently.
