In this paper, the authors propose an approximate method of equivalent piecewise linearization for obtaining solutions of vibrations in essentially nonlinear systems. The restoring force characteristic of the system is replaced by an appropriate piecewise-linear one and a solution is obtained for this approximate system. Furthermore, a perturbation method starts from the above obtained solution as a generating solution. The adequacy of the method proposed is demonstrated by comparing approximate solutions by means of this method with exact solutions for elliptic Duffing equations of hard and soft types subjected to elliptic excitation.
