Abstract

A two degrees of freedom nonlinear dynamics model of self-excited vibration induced by dry-friction of brake disk and pads is built firstly, the numerical method is taken to study the impacts of damping on automobile brake groan. The calculation result shows that the variation of damping coefficient and has different influence on automobile brake groan. and all have A critical value, when damping coefficient greater or less than the critical value the brake disk and pad possess the different vibration state respectively.
