| Abstract: | In this paper, fractional calculus is introduced to describe the damping oscillator in viscoelastic material and the fractional nonlinear oscillator equation is established in this paper. Approximate solutions of the fractional equation are obtained using the Adomian decomposition method and with the aid of the symbolic computational system Mathematica. And the relationship between oscillator movement and fractional derivative is also studied. |
