基波平衡法求解大阻尼Duffing方程

THE DUFFING EGUATION WITH LARGE DAMPING SOLVED BY USING FIRST HARMONIC BALANCE METHOD

对于大阻尼非线性系统，作者用基波平衡原理求解．将其应用于大阻尼Ｄｕｆｆｉｎｇ方程时，经计算机计算验证，结果令人满意．

The principle of the first harmonic balance is applied to solve the problem of the non-Linear Vibrating system with large damping.For duffing equation with large damping,the approximmate solution is proved to be satisfsctory when checked against the computer solution.
