Dynamic Analysis of Beams on Nonlinear Foundation Considering the Mass of Foundation to Moving Oscillator
This article presents dynamic analysis of beam on nonlinear foundation to moving oscillator considering the mass of foundation. The beam is assumed as Euler-Bernoulli beam theory with finite length, one span, discretized by finite element method. The nonlinear foundation fully describes dynamic characteristic parameters including the Winkler linear and nonlinear elastic parameters, the Pasternak shear layer parameter, viscous damping and mass density of foundation. The governing equation of the system is solved by the Newmark method in the time domain. A computer program is written in the MATLAB programming language for analyzing the beam’s dynamic behavior by finding the displacement value center of beam and the dynamic factor of the beam. The effect of foundation mass on the behavior of the beams can be determined by examining the parameters of the beams, the foundation and of the moving oscillator.
