Abstract

The dynamic deflection of an elastic beam subject to a constant load that travels periodically (back and forth) along the span of the beam is investigated through a finite element model. Unlike the classical case of load traveling at constant speed in one direction, multiple resonance peaks were observed at speeds that are lower than the classical critical speed. It is also reported that resonance may not exist at the classical critical speed for simply supported beams due to the symmetry of the beam. The results are interpreted in order to understand the variation of dynamic deflection and estimate the critical speeds for different load conditions.
