Abstract
Acording to the characteristic of railway track, this paper established a simple lateral track model to analyses how the lateral stiffness to affect the lateral force and vibration acting on the components of track. From the calculating results, the main frequency of rail and sleeper lateral vibration is low. The lateral stiffness of ballast affects the lateral vibration greatly. This paper analyses theoretically the dynamic response of rail and sleeper vibration under different stiffness. Finally, This paper suggests that we should improve the smoothness of track geometry, and descend the lateral track vibration to meet the need of raising the speed of train.关键词
