N2 - Based on the closed-loop coupling model of brake noise analysis, experiment modal analysis of stationary disc brake system with different brake-line pressures and brake torques applied is conducted. Then a nonlinear optimization process is used to extract closed actual disc-pad coupling contact by minimizing the differences between experimental and model predicted modal frequencies. Thus, the corresponding relation between brake-line pressures and disc-pad contact coupling stiffness values is established. The influence of the disc-pad contact coupling stiffness on systematic unstable tendency is transformed into the influence of the brake-line pressure on high-frequency brake noise tendency. Finally, the influence law of different brake-line pressures at different noise frequency bands can be obtained, which is helpful to put forward active control measures to suppress the disc brake noise.
