Vibration Isolation of the Quarter Car Model of Road Vehicle System using Dynamic Vibration Absorber
Main Article Content
Abstract
In cases where the natural frequencies of vibrations of a vehicle system are closed to the excitation frequencies from the road surface, dynamic vibration absorber provides the vibration isolation by shifting the resonant frequencies of the system. In the present work, the performance of a dynamic vibration absorber is evaluated with two degrees of freedom quarter car model of a road vehicle system when excited with deterministic inputs. The transmissibility of vibrations from the track to the sprung mass, the transfer function of sprung mass acceleration, the transfer function of suspension deflection and the transfer function of tire deflection is determined.
