In this paper we propose an analytical model of nonlinear spring in nonlinear vibration system with gaps used elasto-plasticity solid model and an analytical evaluation model of the nonlinear vibration characteristics by the nonlinear spring model of cubic equation. A yield load is obtained from bending problem of a beam. The deflection curve of a beam is calculated by Eq. (10), a load and the yield load. The load and the displacement of the center of the beam is calculated by Eq. (10) as x=ℓ. The restoring force is obtained by the load and the displacement. The nonlinear vibration characteristics used the analytical evaluation model are agreed with the simulations and the experiments. The restoring force characteristics used the elasto-plasticity solid model are agreed with that of the experimental results. The restoring force characteristics by the analytical model are described by the cubic equation.
