Forced Oscillators,ted nonlinear oscillators. The exact solutions are achieved via tuning approaches, in which the external excitation or the nonlinearity in a restoring force are specially designed to achieve a desired form of the response. An averaging procedure for obtaining approximate solutions for the steady-sta

Nonlinear Isochronous Oscillators,requency of vibration is amplitude-independent, or, in other words, their backbone curve is a straight line, like for the linear oscillator. These techniques include perturbations methods and certain energy considerations.
