Abstract

In present work, the free vibration dynamics of rotating single walled carbon nanotubes is investigated by using Eringen’s nonlocal theory of elastic structures. Transverse flexural vibration of SWCNT embedded in an elastic medium, a rotating cantilever SWCNT and a nanorotor based SWCNTs is elaborated by using the Hamilton principle to obtain governing equations. Generalized differential quadrature method (GDQM) is employed to discretize and resolve the Eigen problem. The effect of small scale, boundary conditions and angular velocity on the dynamic parameters is studied. Obtained results showed that SWCNTs provide exceptional structural properties. Findings of this study can be involved in the design of next generation nanomachines and nano-devices.
