A NOISE SUPPRESSION METHOD BASED ON COMPLEX EIGENVALUE ANALYSIS OF DISC BRAKE VIBRATION (MT)

A NOISE SUPPRESSION METHOD BASED ON COMPLEX EIGENVALUE ANALYSIS OF DISC BRAKE VIBRATION (MT)

Focusing on investigating the brake squeal problem of a disc brake at 3 000 Hz. To this end, the noise of this frequency is reproduced on the bench, the laser Doppler vibration measurement technology is used to obtain the operational deflection shape（ODS） at this frequency. Finite element analysis（F...
