Experimental investigation of low speed disc brake judder vibration
Brake judder is defined as disc or drum deformation-induced vibration which typically occurs at frequency less than 200 Hz. There are two types of brake judder namely, low speed (cold) judder and high speed (hot) judder. These two types of judder are often causing the brake pedal, steering wheel, su...

| Summary: | Brake judder is defined as disc or drum deformation-induced vibration which typically occurs at frequency less than 200 Hz. There are two types of brake judder namely, low speed (cold) judder and high speed (hot) judder. These two types of judder are often causing the brake pedal, steering wheel, suspension or chassis to vibrate. Consequently, it will affect comfort level of the driver and passengers. This paper focuses on the experimental investigation of low speed brake judder. In doing so, a laboratory test rig consists of disc brake unit, steering and suspension systems was used to assess level of brake judder vibration at different wheel turning angles. It was found that brake judder generated slightly high vibration at the steering wheel in the axial direction which led to a little uncomfortable feeling to the driver. |
