Abstract
Nonlinear free vibration for a nano-mechanical oscillator is investigated. The potential energy between one plate with unit area and one infinite plate is derived based on Lennard-Jones formula, the dimensionless variables are introduced, then the state equations and Hamiltonian function of nonlinear free vibration are formulated for the oscillator. The intersection of minus Lennard-Jones force curve and spring force line motivates to analyze the equilibrium positions of nonlinear free vibration. Some significant parameters which can exert effects on equilibrium positions are pointed out. For the given parameters, the quantitative and qualitative analyses to the phase portrait and motion circle of the nonlinear free vibration are made.
