On kinematic and self-excited rail vehicle-track interaction

摘要

AbstractThe paper contains description of dynamical problems connected with the self-excitation and kinematic excitation of rail vehicle and railway track. Some phenomena are presented which may create high loads resulting in track degradation and fatigue of wheelset axles. An alternative approach to rail vehicle hunting is proposed. Examples of experimental investigations are given which show that the dynamical load acting on the track can be much higher than the static load.
