| Summary: | A numerical simulation to calculate the dynamic response of a beam attached with
beam vibration absorber through a viscoelastic layer subjected to a moving load is presented in
this paper. The mathematical model is
formulated by using Euler-Bernoulli theory to calculate the
vertical response of the system. The ffict of the inertia of the moving load is included in the model
to study its effect on the beam response at the mid span. The viscoelastic layer is introduced as
uniformly distributed stiffness and damping and the concept of mixed damping ratio is
implemented which allows the system to be modeled for dffirent rigidity ratio. The response is
calculated using time integration method for dffirent moving mass inertia, rigidity ratio of the
beams and the stffiess and damping of the visco-elastic layer. The effect is investigated for
dffirent values of mass and speed of the moving load |
