摘要
应用能量原理，引入牛顿线性化思想进行迭代，求强非线性Ｌｉｅｎａｒｄ方程的周期解。例子说明本方法行之有效且精度高。
In this paper, according to energy principle and iteration the iterate Newton linearization idea, we find the periodic solutions of strongly nonlinear Lienard equation. The comparison between the results obtained by our method and those by numerical method shows that this method is both effective and of high accuracy. Expressions of the analytical solution can be derived with electric computer.
