Abstract
The purpose of this study is to investigate the response of an elastic beam on a Winkler foundation under a moving load. The load is assumed as a moving harmonic load and the beam is considered as an infinite Bernoulli-Euler beam with constant cross-section. The approach of Winkler foundation for the elastic foundation is very common in the practical applications although it does not accurately represent the continuous characteristic of the foundations. In this model the interaction between the vertical springs is only considered. In the solutions of the problem, the double Fourier Transform is applied and for its invention Inverse Fast Fourier Transform(IFFT) is used. In the numerical example, the effect of the moving load velocity on the dynamic displacement response of the beam is discussed. The maximum deflections of the beam due to the moving load velocities are illustrated.
