| Abstract: | The modified L P method in the study of the strongly nonliear system with single degree of freedom is extended to the system with multi degree of freedom. Using a perturbation expansion presented in this paper, asymptotic solutions of the strongly nonlinear system are obtained. The method can be applied widely. |

| Keywords: | strongly nonlinear system multi degree of freedom perturbation method |
