Abstract
A linearization procedure to estimate the spectral response at various points of a beam-stop system is proposed. The elastic stop is replaced by a spring with stiffness depending on the amplitude of the deflection at the impact location. Performing the expectation of the spectral density function of the linear system with respect to the probability density of the response amplitude (assumed to be a random variable), an estimate of the nonlinear response spectrum is derived. The efficiency of the method is checked by comparing the results with those of numerical simulations.
