一类非线性振动问题的逼近解析解

An Approximate Analytical Solution of a Class of Nonlinear Vibration Problems

本文用Ａｄｏｍｉａｎ分解法求解了一类非线性振动问题，从而不需任何假设条件下得到了逼近解析解。并以Ｄｕｆｉｎｇ方程为例讨论其解。

In this paper,we solved a class of nonlinear vibration under problems by using the Adomian decomposition method and obtain the approximate analytical solution no any assumed conditions as an example,we discussed solution of Duffing equation.
