Abstract

Vibration of railway bridges under high speed trains has shown a possibility that it could be excited by a row of axle forces. Therefore, the simplest model of a bridge is analysed whereby the beam is subjected to a row of axle forces moving with a constant speed. The paper presents both the components of the forced and free vibrations and the conditions of the resonance vibration are derived in the form of critical speeds. The method of integral transformation is applied. The analysis of free vibration presents a rough estimation of the amplitudes for the deflection, bending moment and acceleration of the beam.
