CONTACT DYNAMIC PHENOMENON CHARACTERISTIC TO LOCOMOTIVES

Abstract

Smooth and safe guiding of wheel sets in curves and keeping them sable require a small tolerance for contact geometry at rail head level. Therefore, grinding track surface to maintain proper conditions for rolling is an essential issue for high speed lines. Railway vehicles lateral oscillation represents a major problem for high speed railways, which can be reduced by modifying vehicles Prud’homme limit and by improving track lateral resistance. Lateral movements cause passenger discomfort, and in some cases because of them the speed average can be reduced. In time, this could be the source for some trouble.
