Reduction of vibration from subway trains in the environment by a passive track vibration isolation system

Abstract

The problem of suppression of vibration caused by subway trains is considered. The reduction of vibration arising during the interaction of rolling stock and rails at the rail—wheel contact is realized by the placement of elastic-inertial shock absorbers with inner inertial elements under a track structure. Enhancement of the vibration isolation effect (by 6–14 dB) with the preservation of the required value of static stiffness is predicted.
