Abstract

In this paper, we implement a new analytical technique, He’s variational iteration method, for some strongly nonlinear oscillations. A correction functional is constructed by using a general Lagrange multiplier, which can be identified via the variational theory. The obtained approximate solutions and periods are compared with exact or numerical results to verify the effectiveness and accuracy of the method.
