TL;DR: In this article, a review of state-of-the-art studies on brake vibration and noise is presented, focusing on the still-open questions that appear crucial from the perspective of a leading brake manufacturer.
Abstract: Several state of the art papers and even books on brake vibration and/or noise have been presented in the literature. Many of them have analytically and sharply accounted for the impressive amount of research undertaken on this topic. This state of the art review focuses on the still-open questions that appear crucial from the perspective of a leading brake manufacturer. The paper deals with the phenomena of brake vibration and/or noise, the experimental and theoretical methods for studying such phenomena, and the actions that are identified to be necessary to definitely solve the addressed problem. Key topics are the modelling of friction, the modelling of the dynamics of the brake as a non-linear system subjected to deterministic or random (parametric) excitation, the proper modelling of the contact between the disc and the pad, and the experimental validation of the mathematical models.

TL;DR: In this article, the presence of pure imaginary eigenvalues of the partially damped vibrating systems is treated and the number of such eigen values is determined using the rank of a matrix which is directly related to the system matrices.

TL;DR: In this article, linear vibrating systems with symmetric positive definite matrices and damping matrices are studied, in which the inertia and stiffness matrix are symmetric and the damping matrix is symmetric====== positive semi-definite, respectively.
Abstract: In this paper, linear vibrating systems, in which the inertia and stiffness matrices are symmetric positive definite and the damping matrix is symmetric positive semi-definite, are studied. Such a system may possess undamped modes, in which case the system is said to have residual motion. Several formulae for the number of independent undamped modes, associated with purely imaginary eigenvalues of the system, are derived. The main results formulated for symmetric systems are then generalized to asymmetric and symmetrizable systems. Several examples are used to illustrate the validity and application of the present results.
