INFLUENCE OF VARIOUS ANOMALIES IN THE VEHICLE AND TRACK PARAMETERS ON THE POSSIBILITY OF DERAILMENT

A detailed non linear model of the four-axle real vehicle, considering both vertical and lateral vibrations has been proposed. Inertial and elastic-viscous properties of the track have been taken into account. Comparison of the theoretical investigations and on-track tests has confirmed the rather good authenticity of the model. The calculations for anomalies either in track or in vehicle parameters as well as for their combinations have been performed
