Experimental Investigation into Friction- Vibration Coupling Characteristics of Vehicle Disc Brake
|
Abstract:
The friction and vibration coupling effect of disc brake was investigated using order analysis and wavelet transformation of brake torque variation and brake pressure variation,which were measured from 9 kinds of disc brakes with various disc thickness variation(DTV) and surface runout(SRO) combination under four brake pressure levels on a brake dynamometer test rig.The brake disc DTV and SRO caused pulsation of normal force and resulted in oscillation of friction coefficient,and that friction coefficient o...
