    Friction Induced Vibration: Brake Moan

    Friction Induced Vibration: Brake Moan


    Techniques have been developed to model friction induced vibration and these were applied to the brake moan of a vehicle. A vehicle system model and the MSC/NASTRAN solutions for geometric nonlinear and complex modes were modified by DMAP for friction input. To assess stability, a position of steady sliding equilibrium was found. Then a complex modes solution was done to find negatively damped modes. Mode shape animation of all the unstable modes showed that there was a 90° out of phase vibration. This produced a design modification on a test vehicle which stabilized the vibration and eliminated brake moan.
