Abstract
Automobile brake squeal noise, which is a nonlinear, friction induced vibration in the frequency range of 1 to 16 ㎑, still remains a major problem for the automotive industry. This paper presents experimental investigations into the application of “dither” control for active noise control and suppression of automobile disc brake squeal. Dither is a concept of active control introducing high-frequency control effects into a system to suppress a lower-frequency disturbance. A specially designed brake system was built and the dither control was applied by a piezoelectric stack actuator in the piston of a floating caliper brake. The results indicate that dither control could effectively suppress the brake squeal noise by 5 dB to 10 dB and the squeal occurrence by up to 60 %.
