Numerical analysis of automotive disc brake squeal: a review
TLDR
In this paper, the authors reviewed numerical methods and analysis procedures used in the study of automotive disc brake squeal and found that the complex eigenvalue analysis is still the approach favored by the automotive industry and the transient analysis is gaining increasing popularity.Abstract:
This paper reviews numerical methods and analysis procedures used in the study of automotive disc brake squeal. It covers two major approaches used in the automotive industry, the complex eigenvalue analysis and the transient analysis. The advantages and limitations of each approach are examined. This review can help analysts to choose right methods and make decisions on new areas of method development. It points out some outstanding issues in modelling and analysis of disc brake squeal and proposes new research topics. It is found that the complex eigenvalue analysis is still the approach favoured by the automotive industry and the transient analysis is gaining increasing popularity.read more

Brake squeal: Linear and nonlinear numerical approaches
TL;DR: In this paper, the authors present the integration of two different numerical procedures to identify the mechanism bringing to brake instability and to analyse its dynamics, and the two models are compared and the onset of squeal is predicted both in the frequency domain by the linear model and in the time domain by a nonlinear one.

Complex eigenvalue analysis and dynamic transient analysis in predicting disc brake squeal
TL;DR: In this article, a detailed three-dimensional finite element model of a real disc brake is developed and three different contact regimes are examined in order to assess the best correlation between the two methodologies.

Transient non-linear dynamic analysis of automotive disc brake squeal – On the need to consider both stability and non-linear analysis
TL;DR: In this paper, the authors investigated the contribution of fundamental frequencies and harmonic components in non-linear transient and stationary dynamics for disc brake system subjected to single and multi-instabilities and showed that an under-estimation of the unstable modes observed in the nonlinear time simulation can be calculated by the stability analysis.

Contact surface topography and system dynamics of brake squeal
TL;DR: In this article, an experimental tribological analysis performed in parallel to the dynamic one and aimed to highlight the role of the contact problems in the brake squeal phenomena was presented, showing that the surface topography after squeal, by revealing several fatigue evidences, points out the possible increasing of wear rates that are consequent to the squeal vibrations.

Chaos in brake squeal noise
TL;DR: In this paper, the authors analyzed the brake squeal data obtained from a full brake system on a noise dynamometer with nonlinear analysis techniques and showed that lower dimensional attractors are isolated and quantified by dynamic invariants such as correlation dimension estimates or Lyapunov exponents.
