摘要
The Optimal Variational Method (OVM) is introduced and applied for calculating approximate periodic solutions of "truly nonlinear oscillators". The main advantage of this procedure consists in that it provides a convenient way to control the convergence of approximate solutions in a very rigorous way and allows adjustment of convergence regions where necessary. This approach does not depend upon any small or large parameters. A very good agreement was found between approximate and numerical solution, which proves that OVM is very efficient and accurate.
