摘要

为了研究碳纳米线的振动特性，建立了弹性弦-弹性壳模型。该模型预测，由于c链的弯曲刚度可以忽略不计，因此c链与最内层管之间不会发生非同轴振动。此外，对于周向波数2 (n=2)， c链对与径向振型相关的最低频率的影响最为显著。特别是，本模型预测的c链对轴对称径向呼吸频率(n=0)的影响与文献中已知的实验和建模结果基本一致。

Vibration and buckling of a carbon nanotube inserted with a carbon chain

An elastic string-elastic shell model is developed to study vibration behaviors of a carbon nanowire. The present model predicts that non-coaxial vibration between the C-chain and the innermost tube does not occur due to negligible bending rigidity of the C-chain. In addition, it is found that the C-chain has most significant effect on the lowest frequency associated with radial vibration mode for circumferential wave-number 2 (n=2). In particular, the effect of the C-chain on axisymmetric radial breathing frequencies (n=0) predicted by the present model is found to be in reasonable agreement with known experimental and modeling results available in the literature.
