Finite element analysis on squeal-noise in railway applications [PDF]

open access: yesFME Transactions, 2018
In this paper, we present the results of an experimental investigation on squeal noise emitted by a disc brake for railway applications. The measurement, that show in an evident manner the onset of instability forms during the braking phase were made on ...

Squeal Analysis of Disc Brake Using Analytical-FE Squeal Model

open access: yesJournal of the Korea Academia-Industrial cooperation Society, 2014
This paper presents the analytical-FE (finite element) squeal model, which can provide the efficient simulation time and accuracy. The system geometry and the extraction of the vibration modes were constructed using the finite element method. Instead, the friction contact model was derived from theoretical contact kinematics of the rotating disc and ...

Modal Analysis of the Floating Caliper Brake Assembly through Complex Eigenvalue Analysis: A Weighted Bolt Approach

open access: yesJournal of Mechanical Engineering
This study demonstrates the application of Complex Eigenvalue Analysis (CEA) to optimize a weighted bolt that targets unstable frequencies in a floating caliper brake assembly. A commercial automobile brake assembly undergoes experimental modal analysis,

Probabilistic Prediction of Wheel Squeal under Field Humidity Variation [PDF]

open access: yes, 2010
This research examines the effect of changes in coefficient of friction due to humidity on the likelihood of wheel squeal events occurring in practice. Theoretical mechanics based modeling is developed and compared to a database of field measurements of ...

Effects of rail dynamics and friction characteristics on curve squeal

open access: yes, 2016
Curve squeal in railway vehicles is an instability mechanism that arises in tight curves under certain running and environmental conditions. In developing a model the most important elements are the characterisation of friction coupled with an accurate ...

Interaction between vibration and friction of Coulomb friction contact surfaces [PDF]

open access: yes, 2007
Contact surfaces with dry Coulomb friction are present in many engineering structures. A two dimensional model of these systems in the form of a block-incline is proposed.
