On the Analysis of Brake Squeal Propensity Using Finite Element Method 2000-01-2765

In the present work, the finite element method is used to analyze the friction-induced vibration of brake systems, which may lead to squeal. A new approach is proposed to model the friction interaction at the rotor/pad interface, leading to the dynamic equations which well represent the dynamic characteristics of brake systems. The complex eigenvalue analysis method is then employed to detect the unstable modes of the system.The analytical method presented can be applied to both disk brake and drum brake systems. Some application results are presented and discussed.
