Abstract

Journal of Vibration and Control, Ahead of Print.
The urban high-speed rail transit system generates excessive environmental vibrations, causing discomfort and damage to contact elements. This study introduces a novel non-obstructive particle damping phononic crystal vibration isolator (NOPD-PCVI) for a ...
