Resonant frequencies of cantilevered (8,8)(3,3) double-walled carbon nanotube (DWCNT) resonators are investigated via classical molecular dynamics simulation. The interwall van der Walls forces as a nonlinear function had a great effect on noncoaxial vibration of DWCNT resonators. Bandwidths of DWCNT resonators with short outer walls were similar with each other irregardless to the structural difference. The frequency trends of DWCNT resonators with short outer wall were affected by the outer wall length. The vibration of the DWCNT resonator with short outer wall was very closely related to the vibration of the inner CNT in the stripped region.
通过经典分子动力学模拟研究了悬臂式(8,8)(3,3)双壁碳纳米管(DWCNT)谐振器的共振频率。作为非线性函数的壁间范德华力对DWCNT谐振器的非同轴振动有很大影响。外壁较短的DWCNT谐振器的带宽彼此相似，与结构差异无关。外壁较短的DWCNT谐振器的频率趋势受外壁长度影响。外壁较短的DWCNT谐振器的振动与剥离区域内的内碳纳米管的振动密切相关。
