The paper presents a modified Lindstedt-Poincare (ML-P) method with multiple time scales to extend the applicability of the perturbation technique for computation of almost periodic oscillations in damped multiple-degree-of-freedom (N-DOF) dynamical systems with strongly cubic non-linearities. The results of ML-P method with multiple time scales are compared with results of the incremental harmonic balance (IHB) method to show the efficiency and advantages of the proposed method.

This paper treats the analytical version of the harmonic balance (HB) method for the analysis of the periodic response of nonlinear, nonautonomous oscillators with harmonic excitation. The equation of fundamental resonance is obtained as early as in the first iteration of the method, where the fundamental harmonic term is taken into account.
