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 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...
متن کاملParameter Determination of a Minimal Model for Brake Squeal
In the research into the mechanism of brake squeal, minimal models with two degrees of freedom (DoFs) are widely used. Compared with the finite element method, the minimal model is more concise and efficient, making it easier to analyze the effect of parameters. However, how to accurately determine its kinetic parameters is rarely reported in the literature. In this paper, firstly, the finite e...
