EINIGE PROBLEME DER VERBINDUNG ZWISCHEN EINEM DURCH ZUFÄLLIGEN FEHLER BELASTETEN PUNKT ODER ABSCHNITT EINER EISENBAHNSTRECKE UND DER MASSGEBENDEN KINEMATISCHEN BEANSPRUCHUNG

Abstract

The fundamental task of kinematical investigation of railway tracks is that in a given position or interval of the track in respect to the view of acceleration no bigger stress can arise than the given acceleration limit or the given limit by the examination of the third kinematical characteristic of movement. In idealised case the railway track consists of regular straight intervals, regular curves, and regular transition curves. Conclusions drawn from the investigation of the idealised case can greatly deviate from facts supported by real and experimental measure- ment. Our contemporary measurement facilities only restrictedly enable the kinematical stresses to be directly measured therefore in such cases they can be indirectly examined. The theoretical estimation for standard stresses can be applied in practice, if the distribu- tion of the standard stresses of the extreme error intervals and the suitable circumstances of cycles lengths is available.
