Static as well as dynamic analyses have been performed on clamped-clamped carbon nanotube (CNT) resonator.
The nonlinear CNT model is investigated with a novel discretization technique: a differential quadrature method (DQM) to discretize the spatial variables and a finite difference method (FDM) for limit-cycle solutions.
Parametric study is performed by varying the electric load, as well as the initial curvature (due to fabrication).
It is found that the pull-in voltage decreases nonlinearly with initial curvature and linearly with residual stresses.
The eigenvalue problem is also solved to obtain the bending natural frequencies of the system as function of the DC voltage as well as the initial curvature of the CNT.
Frequency-response curves near some selected resonant frequencies are plotted to better understand the nanotubes' dynamic behavior.
Different linear and nonlinear phenomena are depicted such as dynamic pull-in, hardening, and softening behavior and veering of the odd modes.
We have found that even when exciting the CNT near its first natural frequency, the vibration mode located at the veering process significantly alters the CNT's motion and hence may decrease its overall quality factor.
