Abstract

Investigation of beams under moving loads on foundation problems have been studying for years. In this paper first of all a mathematical model of a simply-supported Euler-Bernoulli beam under moving load is presented. Moving load is concentrated load that forced on midpoint of the beam and foundation model is viscoelastic foundation. By using Galerkin Method, equation of motion is turned from PDEs to ODEs. After the solving equations of motion, displacement of the midpoint of the beam is plotted in Mathematica. Lastly, dynamic response of the beam is investigated depending on different rail pads, velocities of the force and support lengths.
