| Abstract: | Through the numerical experiment,it is discovered that there exists three states such as damped oscillation,critical damped oscillation and over-damped oscillation while a cubic oscillator moves in linear damping force.The quantitative formula of the critical damping constant varied with system parameters and initial conditions has been obtained.The attenuation rules of the displacement of a cubic oscillator under damped states has been found. |
