DYNAMIC CHARACTERISTIC OF WHEEL AND WHEEL/RAIL NOISE

Abstract

The noise and vibration characteristics produced on a 2/5ths scale wheel-rail simulator device and by axial excitation of a wheel, not otherwise supported, produced similar results. Theoretical study was then made of the excitation of the wheel rim from its hub and was seen adequate for studies of noise suppression of wheels. This report indicates the method of analysis and describes essential details clarified by numerical computation.
