Complex eigenvalue analysis and dynamic transient analysis in predicting disc brake squeal
International Journal of Vehicle Noise and Vibration, 2006 There are typically two different methodologies that can be used to predict squeal in a disc brake, i.e., complex eigenvalue analysis and dynamic transient analysis. The positive real parts of complex eigenvalues indicate the degree of instability of the disc brake and are thought to associate with squeal occurrence or noise intensity.

Complex eigenvalue analysis and parameters analysis to investigate the formation of railhead corrugation in sharp curves [PDF]
Wear, 2020 Rail corrugation, a quasi-sinusoidal irregularity of the rail head, is a common issue experienced throughout the railway networks worldwide. It generally leads to high wheel-rail dynamic loads, increased noise emission, and poor ride comfort.

Complex eigenvalue analysis of railway wheel/rail squeal
International Journal of Engineering, Science and Technology, 2016 Wheel/rail squeal noise of trains is one of the challenging problems of trains, but a successful model for the squeal problem has not been presented until now. In this study, a new approach was presented to investigate the basic mechanism of the wheel/rail squeal noise, using complex eigenvalue analysis by the finite element method.

Complex eigenvalue analysis of rotors by the transfer coefficient method.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 This paper proposes a new method for rotor dynamics calculations, called the transfer coefficient method, which is more convenient than the conventional transfer matrix method. By treating only the displacement as the independent variable, where both the

Complex Eigenvalue Analysis of Multibody Problems via Sparsity-Preserving Krylov–Schur Iterations
Machines, 2023 In this work, we discuss the numerical challenges involved in the computation of the complex eigenvalues of damped multi-flexible-body problems. Aiming at the highest generality, the candidate method must be able to deal with arbitrary rigid body modes ...

A Study on the Influence of Dominant Parameters Related to Brake Squeal in the Brake System with the Flexible Pad [PDF]
한국정밀공학회지, 2022 The brake squeal noise is a high-frequency noise over 1 kHz range generated by the contact between the brake pad and the disk. The purpose of this paper was to investigate the behavior of the squeal noise characteristics of the brake system from an ...
