چکیده مقاله
Nonlocal vibration of double-smart nanobeam-systems (DSNBSs) under a moving
nanoparticle is investigated in the present study based on Timoshenko beam model. The
two smart nanobeams (SNB) are coupled by an enclosing elastic medium which is
simulated by Pasternak foundation. The energy method and Hamilton’s principle are used
to establish the equations of motion. The detailed parametric study is conducted, focusing
on the combined effects of the nonlocal parameter, elastic medium coefficients, external
voltage, length of SNB and the mass of attached nanoparticle on the frequency of
piezoelectric nanobeam. The results depict that the imposed external voltage is an effective
controlling parameter for vibration of the piezoelectric nanobeam. Also increase in the
mass of attached nanoparticle gives rise to a decrease in the natural frequency. This study
might be useful for the design and smart control of nano-devices.
