Analysis of nonlinear oscillation systems using He's variational approach

Abstract

This paper applies a new variational approach proposed by Ji-Huan He for nonlinear oscillators. Two examples are given to illustrate the effectiveness and convenience of the method. The obtained results are valid for the whole solution domain with high accuracy. The method can be easily extended to other strongly nonlinear oscillations and it can be found widely applicable in engineering and science. © 2008 IOP Publishing Ltd.
