摘要: 研究了一类特殊的非简谐运动——对称双弹性振子的横振动,得到了在微振动条件下的严格解,发现其运动周期与振幅的大小成反比,其波形对于简谐波的形变系数较小,且与振幅的大小无关。

关键词: 对称双弹性振子, 微小横振动, 周期, 形变

Abstract: A kind of special non-harmonic motion, i.e. , the transversal vibration of the symmetric double elastic oscillators is discussed, and the exact solutions under the condition of small amplitudes are obtained. It turns out that the periods is inversely proportional to the amplitudes and the deformation of the waves is independent to the amplitudes.

Key words: double elastic oscillator, transversal vibration, periods, deformation
