摘要: Abstract Paddle-type and double-sided nanostructures are potential for use as accelerometers in flying vehicles aerospace applications. Herein the pull-in instability of cantilever paddle-type sensors Casimir regime investigated under acceleration. The D׳Alembert principle is employed to transform accelerating system into an equivalent static by incorporating force. Based on couple stress theory (CST), size-dependent constitutive equations derived. governing nonlinear solved two approaches, i.e. modified variational iteration method finite difference method. influences force, geometrical parameters, acceleration size phenomenon performance have been demonstrated. obtained results beneficial design fabricate accelerometers.
