Abstract

Car body vibrations caused by the track irregularities needs to be suppressed in order to provide a good ride quality. Although there are numerous researches on active suspension systems, practical implementations of the active suspension systems for vertical car body vibrations are limited. In this study, a modified Delayed Resonator (DR) with delayed speed feedback is used as an active vibration absorber for suppressing vertical vibrations of the car body. In order to maintain suppression at a wide frequency range a new term is added to a classical DR which is affecting on the natural frequency of the vehicle.
