Abstract

Spinning nanotubes are the main part of different high precision nano-machines such as nano sensors, nano motors, and nano pumps. Nanotubes experience various types of loads in such devices. In this paper, different type of instability for a spinning nanotube under tangential load is investigated. For this purpose, Euler and Timoshenko nonlocal beam theory is used. Equations of motion are obtained by applying Hamilton’s principle on the energy terms of nanotube by considering rotational velocity and compressive tangential load. Numerical results are exactly calculated for different parameters and are checked by comparing them with literature. Results show that there are two type of instability for simply supported spinning nanotubes as divergent and flutter, generally. Also, effects of different nonlocal parameter, geometry and rotational speed on these instabilities are investigated, comprehensively. It is approved that nonlocal parameter has significant effect on both of the instabilities.
