摘要
研究具有奇非线性单自由度保守系统的非线性振动 .通过改进Mickens的迭代法建立频率的两个解析逼近公式 。
This paper deals with nonlinear oscillations of conservative single degree of freedom systems with odd nonlinearity. A modified Mickens' iteration procedure is proposed to establish two analytical approximate formulas for the frequency. The two formulas are valid for small as well as large amplitude of oscillation.
