IMPACT OF LONGITUDINAL STIFFNESS OF RAIL TRACK ON THE SLIDING OF LOCOMOTIVE WHEEL PAIR
Abstract
Locomotive motion in traction mode is accompanied by wheel pair sliding along the rail, sometimes it results in slippage. This process which is rather dangerous depends on many factors, including, in authors’ opinion, longitudinal stiffness of the track.
The article describes an experimental method of determining of track longitudinal stiffness. The results here-of give the possibility to calculate power losses caused by rail inelastic drift. The procedure includes dynamic analysis of motion of locomotive wheel pair in the case of its run-over the compressed section of track and calculation of wheel pair sliding speed regarding the rail.
The authors also examine auxiliary rotary motion of wheel pair during its interaction with the rails and sliding effect caused by it.
