Abstract:

This paper presents an approximate method for the time-domain analysis of vibration data obtained from the response of nonlinear multidegree-of-freedom dynamic systems that are undergoing nonlinear deformations. In addition to providing a convenient procedure for the nonparametric identification of arbitrarily nonlinear structural systems, the proposed data-processing method furnishes a rational approach for a systematic procedure of model-order reduction in nonlinear systems.
