Notes:
Static and dynamic characteristic of carbon nanotube is analyzed by molecular dynamicsimulation. Static analysis show that maximum deflection of carbon nanotube appears at 0.033nmdistance from free end of cantilever. When the value of driving voltage is less, the flexibility ismore important, then the stiffness increase with the voltage increasing, and the collapse structure orhole appear on carbon nanobute. Under low pressure condition, deflection difference onequi-increase of pressure between no damping and damping simulation is larger than that on highpressure. The results of forced vibration indicate that system response consist of transient andsteady-state response. With steps of molecular dynamic simulation increasing, transient responsedisappears gradually, so system response includes only steady-state response, which is simpleharmonic vibration with the same frequency as excitation force. These results are in accord with theclassical vibration theory. Moreover they will provide theoretic foundation for designing ofnanostructure device
