Improving brake squeal propensitiy prediction by model updating
TL;DR: In this study, a full brake system is modally updated at the component level and then at the subassembly level (pad assembly alone, pad in bracket).

Investigation on evolvement of dynamic behaviors of ship stern shaft-bearing system under the different rub-impact states based on attractor
TL;DR: In this article, the authors investigated the evolution of dynamic behavior from the ship stern shaft bearing system, and the attractor theory was introduced to investigate the evolvement of dynamic behaviour from the system.
Uncertainty analysis for the prediction of disc brake squeal propensity
Z Zhang,Sebastian Oberst,Jcs Lai +2 more
TL;DR: In this article, a stochastic approach, incorporating uncertainties in the surface roughness of the lining, material properties and the friction coefficient, is applied to predict the squeal propensity of a full disc brake system by using CEA on a finite element model updated by experimental modal testing results.
Towards the understanding of hip squeak in total hip arthroplasty using analytical contact models with uncertainty
TL;DR: In this paper, an analytical model is proposed to study the onset of friction-induced vibrations in a simplified hemispherical hip stem rubbing in its bearing by varying the contact area, and preliminary results of the complex eigenvalue analysis and stick-slip motion analysis indicate that an increased contact fosters the development of instabilities, even at very small values of the friction coefficient owing to large local contact pressures.

Prediction and suppression of chaotic instability in brake squeal
TL;DR: Conservative analytical conditions for brake squeal chaos are developed and verified numerically over a range of sprag angles and brake pressures for fundamental and real brake systems, and the predictive model is used to identify and quantify means to suppress brake Squeal chaos to unlikely, excessive friction levels.

Chaos in dynamical systems
TL;DR: In the new edition of this classic textbook, the most important change is the addition of a completely new chapter on control and synchronization of chaos as mentioned in this paper, which will be of interest to advanced undergraduates and graduate students in science, engineering and mathematics taking courses in chaotic dynamics, as well as to researchers in the subject.

Recurrence plots for the analysis of complex systems
TL;DR: The aim of this work is to provide the readers with the know how for the application of recurrence plot based methods in their own field of research, and detail the analysis of data and indicate possible difficulties and pitfalls.
Nonlinear Time Series Analysis

TL;DR: In this article, the authors discuss the use of non-linear methods when determinism is weak and apply them to the problem of neighbor search in the presence of chaotic data and noise.

Nonlinear Time Series Analysis.
TL;DR: This thesis applies neural network feature selection techniques to multivariate time series data to improve prediction of a target time series and results indicate that the Stochastics and RSI indicators result in better prediction results than the moving averages.
