Disk brake squeal prediction using the ABLE algorithm
Disk brake squeal noise is mainly due to unstable friction-induced vibration. A typical disk brake system includes two pads, a rotor, a caliper and a piston. In order to predict if a disk brake system will generate squeal, the finite element method (FEM) is used to simulate the system. At the contact interfaces between the pads and the rotor, the normal displacement is continuous and Coulomb’s ...

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 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...
