A Study of Friction Modeling for Friction-induced Vibration Simulation.

We developed and proposed the extended friction model which can consider the instantaneous sliding vector and velocity dependency of friction coefficient as a linear damping effect. By definition of this model, line pressure and braking speed can be taken into account in the brake squeal simulation by using FEM. Also the tendency of brake squeal characteristics by deploying the extended friction model to Multi DOF is presented. Furthermore, the tendency of brake squeal characteristics by the adoption of partial shims that changes the contact pressure distribution is presented. [ABSTRACT FROM AUTHOR]
