SIMULTANEOUS DETECTIING METHOD OF THE NONLINEAR RESTORING AND EXCITATION OF A FORCED NONLINEAR OSCILLATION

摘要

The present invention provides nonlinear restoration for a machine system receiving a repeated load and an estimation method for a load size of an external cycle. As stated above, according to the present invention, the nonlinear restoration for a machine system receiving a repeated load and the estimation method for a load size of an external cycle enable nonlinear restoration and external exciting characteristics to be estimated at the same time in case a generally and periodically repeated load of a nonlinear machine system is provided as an exciting force.
