Abstract

In this paper, He’s parameter-expanding method (PEM) is used to obtain the nonlinear frequency–amplitude relationship of nonlinear oscillators. The obtained result is valid even for the case when the amplitude tends to infinite; revealing that He’s method is very effective and convenient.
