Verification of Reduction Effect of Vertical Vibration of Car-body by High-damping Elastic Support of Under-floor Equipment

Abstract

We are developing high-damping elastic support of under-floor equipment as one method for reducing vertical car-body vibrations. In this study, two types of excitation test were performed using an actual vehicle. Firstly, we conducted excitation tests in the rolling stock testing plant to verify the effect of the elastically supported mass on the reduction of the elastic vibration of car-body. Secondly, to examine the vibration isolation performance of the developed rubber mount, we conducted stationary excitation tests using a vibration exciter.
