In this study, the stability and vibration analyses of a spinning smart nanotube under electrical loads are examined for first time. The structure is made from single-walled zinc oxide (SWZnONT) due to its extraordinary piezoelectric magnetic properties, which have great potential use as rotating component in nanoelectromechanical systems (NEMS). To achieve aim, nonlocal strain gradient theory Maxwell's electrostatic equations used capture structure's small-scale effects, respectively. addition, nanotube's structural model based on Euler–Bernoulli beam theory, deriving governing boundary conditions via Hamilton principle. A technique employing Galerkin-based closed-form solutions utilized solve motion get response nanotube. Finally, effects material length scale, parameter, speed, external voltage, natural frequency critical rotational speed investigated. study results indicate that applying an voltage SWZnONT effectively adjusts enhances stability.
