Dynamical investigation of effects of variable damper settings induced brake pressure oscillations on axle and wheel oscillations during ABS-braking based on experimental study



In this study, the effects of variable damping setting induced brake pressure oscillations on axle and wheel oscillations have been experimentally explored. For this, antilock brake system (ABS) tests are conducted on wet and slippery rough roads with hard, medium-hard and soft shock absorbers. In ABS tests, the axle height, the longitudinal and vertical axle accelerations have been measured. The results are discussed for time and frequency responses of axle vibrations in vertical and longitudinal direction. The time responses are separately considered for high and low piston velocities of damper. Also, in order to occur the effects of changes in ABS-brake pressure on axle vibrations, novel rules are designed. These rules are based on the integration of suspension dynamics into braking dynamics. The results show that the brake pressure is distinctly changed by variable damping settings. In time responses, these differences are determined by changes in time period and magnitude of brake pressure during build-up and reduction process. In frequency responses, the brake pressure differences are occurred by the different change frequencies of brake pressure causing resonance at axle vibrations. Also, the changes in magnitude of resonance peaks have determined the effects of brake pressure changes on axle vibrations. As a result, it is possible to damp the oscillations by changing the magnitude and frequency of brake pressure by means of the damper settings during ABS-braking.
