On Modeling of Car’s Wheel Set Movement

Abstract
The article considers a refined mathematical model of motion of a wheel set with a variable structure of a system of nonlinear differential equations, as well as design diagrams describing interaction of elements of a railway vehicle and a track. The model also takes into account factors that are relevant for speed movement, such as gyroscopic moment and imbalance of a wheel set. The «vehicle-track» system is presented as complex and multi-mass one, with a different structure of interconnections. The track is studied in the form of a free curved surface on the Winkler base as a system of separate inertial elastic supports with dry friction dampers. The model will allow to obtain the correct quantitative results, to evaluate the dynamic properties of rolling stock.
