Abstract
A new analytical method called He’s variational iteration method VIM is introduced to be applied to solve nonlinear BenjaminBonaMahonyBurgers BBMB equations and free vibration of a nonlinear system having combined linear and nonlinear springs in series in this article In this method general Lagrange multipliers are introduced to construct correction functionals for the problems The multipliers can be identified optimally via the variational theory The results are compared with the results of the homotopy analysis method and also with the exact solution He’s Variational iteration method in this problem functions so better than the homotopy analysis method and exact solutions one of them in per section
