Numerical study on the vibration characteristics of automobile brake disk and pad
Based on the review of researches on the vibration and noise related to automobile brake, a four degrees of freedom nonlinear dynamics model of brake disk and pads is established, the stability of vibration system at the equilibrium points is analyzed. Finally the numerical method is taken to study the impacts of brake pressure, shape parameter and the brake disk's initial velocity on the vibration characteristics of brake disk and pads. The calculation result shows that with the increase of brake pressure and/or the decrease of brake disk's initial velocity, the tangent direction vibration was weakened, the variety of shape parameter has (be of) complicated nonlinear dynamics characteristics, while the normal direction vibration have no distinct changes.
