چکیده
|
A nonlinear oscillator arising in the microelectromechanical system is complex and it is difficult to obtain a variational principle. this paper begins with a wrong variational formulation and uses the semiinverse method to obtain a genuine variational principle. additionally, this paper gives simple formula for the fast frequency estimation of the nonlinear oscillator. only simple calculation is needed to have a relatively high accuracy results when compared with the other methods.
