Abstract
A time-domain procedure for the identification of nonlinear vibrating structures, presented in a companion paper, is applied to a “calibration” problem which incorporates realistic test situations and nonlinear structural characteristics widely encountered in the applied mechanics field. The “data” set is analyzed to develop suitable, approximate nonlinear system representations. Subsequently, a “validation” test is conducted to demonstrate the range of validity of the method under discussion. It is shown that the procedure furnishes a convenient means for constructing reduced-order nonlinear nonparametric mathematical models of reasonably high fidelity in regard to reproducing the response of the test article under dynamic loads that differ from the identification test loads.
