Front Wheel Vibrations: A Hydraulic Point of View - Models and First Results

Even if the brake judder is an often analyzed problem from the mechanical point of view, its influence on the hydraulic elements such as the braking and steering systems is not fully established. The aim of this paper is to present models of the hydraulic components connected to a model of the front suspension and thus having a view of the influence of these hydraulic elements on the amplification of the brake judder vibrations. Each models of the front suspension, the braking circuit and the hydraulically powered steering assistance are validated separately versus or measurements or other softwares. The introduction of the disc thickness variation (DTV) generates the braking judder of interest. Some first simulation results are shown to see couplings or influence of hydraulic components on vibration propagations.
