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, 这些公式既适用于小振幅又适用于大振幅.

关键词: 保守系统, 非线性振动, 频率, Mickens迭代方法

Abstract: This paper deals with nonlinear oscillations of conservative single-degree-of-freedom systems with odd nonlinearity. A modified Mick ens' iteration procedure is proposed to establish two analytical approximate for mulas for the frequency. The two formulas are valid for small as well as large a mplitude of oscillation.

Key words: conservative system, nonlinear oscillation, frequency, Mickens' iteration procedure
