Abstract

The governing equations are solved by the combination of Fourier transform and residue theory. The influence of the beam parameters on the dynamic response is discussed. It is shown that two cut-off frequencies and two critical velocities exist in this double-beam system. The rail has consistently higher displacement response than the slab. Load frequencies have great influence on the both beams. The Doppler Effect is significantly obvious as the load velocity exceeds critical velocities.
