Vibration Reduction and Noise Suppression for Urban Railways with a Wheelset Dynamic Vibration Absorber
Publication: Resilience and Sustainable Transportation Systems
ABSTRACT
This paper proposes a novel method of vibration mitigation and noise suppression at the source by using a wheelset dynamic vibration absorber. The wheelset dynamic vibration absorber is mounted on the wheelset axle to reduce the vertical vibration and wheel noise of the urban rail wheelset. Previous studies on dynamic vibration absorber for rail transit systems are reviewed. The theoretical modeling of the absorber is introduced in detail to reveal the relationship between wheel vibration and wheelset noise. To make the best use of the space, the structural design is developed to illustrate the basic principles and the advantages of the arrangement. The parameter design is also investigated to indicate three steps of the absorber. And then a comparison of wheel vibration and noise with and without the WDVA is obtained. The results show that the wheelset dynamic vibration absorber has the potential to reduce the vertical vibration of the wheelset at low frequencies. Furthermore, the absorber is found to suppress the generation of wheel noise and produce good noise suppression effects at high frequencies.
