Development of Longitudinal Excitation Suppression Devices for Reducing Car-body Elastic Vibrations in Bullet Trains

This study proposes a method to reduce car body elastic vibrations in bullet trains caused by longitudinal excitation via traction devices and yaw dampers. We devised two vibration reduction devices—"displacement-dependent rubber bushes" and "mesh springs" to suppress the longitudinal excitation force. We conducted excitation tests using a Shinkansen (bullet train)...
