This paper deals with nonlinear vibration of a continuum system with gaps under random waves considered collision phenomena. In order to investigate this nonlinear vibration characteristic, experiments are carried out with an experimental apparatus consisting of a nonlinear vibration system. An analytical model is proposed based on the restoring force characteristics in the experiments. This analytical model is used for the simulation analysis. Then results show differences between the experiment and the simulation in the R.M.S. value of the response acceleration. In order to investigate this cause, an experimental apparatus for the collision effect is made. Experiments are carried out with this apparatus. It is found that the energy dissipated by collision phenomena causes these results. The with the experimental results.
