We present a method for estimating the (power spectral density) PSD matrix of the stationary response of lightly damped randomly excited multi-degree of fredom mechanical systems with strong non-linear asymmetrical restoring forces. The PSD matrix is deยฎned as the mean value of the PSD matrix respon

Though there are many non-linear systems in use, the experimental modal analysis techniques are based on the linear system. In this paper, an experimental modal analysis technique for a multi-degree-of-freedom system with random parametric excitation and non-linear damping being proportional to the
