Abstract
As for a train running at high speeds in a tunnel, the car-body vibration increases considerably and the ride quality is deteriorated. To improve the ride quality of a train at high speeds, effects of stiffness and damping between vehicle ends are examined. In the case that the restriction between vehicle ends is too strong, however, the curving performance may be deteriorated on sharp curves. In this paper, an analytical model of a train is developed and the ride quality at high speed and the curving performance on a sharp curve are simulated. A potential to improve the ride quality is found by increasing inter-vehicle damping in longitudinal direction without increasing wheel lateral force on sharp curves.
