Variability effects on automotive brake squeal prediction

Abstract : The objective of this paper is to discuss the effect of different kinds of variability such as material properties, interface and boundary conditions and geometric characteristics on squeal prediction of an industrial automotive brake system. Firstly, a focus on the quantification of experimental uncertainty and parametric variability is presented. Secondly, an updating of numerical model of brake components is performed by considering a nominal FE model and associated realistic variability. Finally, numerical simulations are performed for specific combinations of input parameters, identified experimentally. The aim is to highlight the variability effects on complex frequency and transient results and to identify the most significant parameters useful for robustness analysis
