DYNAMICS OF WHEEL-TYRE SUBJECTED TO MOVING OSCILLATING FORCE

Abstract

The subject of the paper is analysis of wheel of a moving railway vehicle which is subjected to a moving oscillating force. Rail ring is treated as a beam of small curvature connected to wheel axle with a Winkler foundation. Bernoulli-Euler and Timoshenko beam model is used. Results are gained using Fourier transformation. Space and space-time graphs, showing wave propagation in subcritical and supercritical zones of excitation, concerning resonance of transverse vibrations, are included.

Keywords:

railway vehicles, waves, oscillating force, railway wheels
