Stability Analysis of CNT Based Nano-Actuator Under Magnetic Field and Rippling Deformation

Objective The widespread use of carbon nanotube-fabricated electromechanical systems has resulted in new operating scenarios for these structures, such as the presence an external magnetic field. Also, rippling can significantly impact performance nanotube-based actuators. These critical phenomena, however, are frequently overlooked theoretical beam models. This paper simulates electromagnetic instability a nano-tube-made actuator subjected to As bending may affect stability performances nano-actuator, influence phenomenon is considered governing equation. van der Waals force incorporated simulation. Methods equation nano-tube-manufactured nano-actuator developed terms moment and lateral forces. Rippling wavelike deflection bent nanotubes on their inner arc. configuration crucial large deformations, both globally locally. classical linear relationship between curvature cannot be employed rippled CNT. Therefore, modified non-linear curvature-moment used model. impacts field, electrical attraction loads. induced transverse load nanotube due constant longitudinal field simulated by using Maxwell electrodynamics equations. Finally, constitute obtained which ordinary differential A semi-analytical solution based Galerkin method presented solve system’s Results proposed model confirmed comparing resulting result experimental data. Then, influences interaction, flux, parameters studied. results demonstrate that reveals reduces deflection. Moreover, imposing decreases voltage system. Similarly, lessens considering effect. Conclusion mathematical established study CNT-made environment. accounts longitudinally suitable body forces interactions. also takes into account bending. demonstrated flux phenomena reduce nano-actuator.
