Effects of rail dynamics and friction characteristics on curve squeal
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 representation of the structural dynamics of the wheel. However, the role played by the dynamics of the rail is not fully understood and it is u...
متن کاملThe Influence of Friction-Induced Damping and Nonlinear Effects on Brake Squeal Analysis
This paper presents numerical studies of friction-induced instabilities of brake systems using complex mode analysis. The complex eigenvalue extraction is performed at a deformed configuration; thus, nonlinear effects are taken into account in the modal analysis. An example case is used to illustrate the importance of friction-induced damping and nonlinear effects in brake squeal analysis. It i...
متن کاملShape Optimization for Brake Squeal
1. Abstract The present paper describes a solution to a non-parametric shape optimization problem of a brake model suppressing squeal noise. The brake model consists of a rotor and a pad between which the Coulomb friction occurs. A main problem is defined as a complex eigenvalue problem of the brake model obtained from the equation of motion. As an objective cost function, we use the positive r...

متن کاملExample Based Mini-Course on Mathematical Modelling: Brake Squeal
Driven by the desire for safety and automobile regulations, there has been a movement from the drum brake system, where braking force is not as predictable, to the disc brake system that still continues to this day. This shift is perhaps most noticeable in the heavy vehicle industry. However, despite the improvements in stopping distance, the open nature of the disc brake system makes it more p...
