| Abstract: | In this paper, using the improved L-P method, the author seeks to solve a class of strongly nonlinear free oscillation problems of a conservative system. On this basis, using the interpolation perturbation method, we progressively study the more general strongly nonlinear free oscillation of a nonconsevative system. Numerical examples are presented. They show that the method of this paper is reliable. |
