Dynamical Behaviour of the Disc Brake Pad 912656

High-frequency brake noise is generated by the contact interaction between the friction surfaces of the brake pad and the brake disc during the braking act, and influenced by the topography, the tribological third body, pressure, temperature, sliding velocity, environmental conditions etc.The solution to this automobile comfort problem can be reached by defined chemical friction material formulations determining the pad topography and therefore the time-dependent self-excited vibration force. With defined starting and boundary conditions this force has to be included into the macro-mechanical model described by analytical and numerical methods.
