Abstract
The invention discloses a method for analyzing nonlinear restoring force characteristic with hysteresis of a machine structure system, capable of easily and high-accurately performing analysis of nonlinear vibration characteristic of the machine structure system having a displacement strain characteristic dependent on a past history. When analysis is performed for the nonlinear restoring force characteristic of the machine structure system, having force-displacement hysteresis, approximate mode analysis is carried out by representing the nonlinear restoring force characteristic having the history by an equivalent linear characteristic.
