On the Numerical Approximation and Simulation of Damped and Undamped Duffing Oscillators

Lydia John Kwari,Joshua Sunday,Joel Nimyel Ndam,Adewale A. James.


Duffing oscillator (damped or undamped) is one of the most significant and classical nonlinear ordinary differential equations in view of its diverse applications in science and engineering. The Duffing oscillator is an equation that has cubic stiffness term regardless of the type of damping or excitation. Over the years, different methods have been developed for the solution of Duffing oscillators. In this paper, a new method is derived for the approximation and simulation of damped and undamped duffing oscillators. In deriving the method, power series was employed as a basis function by carrying out the integration within one-step interval. The results obtained clearly showed that the method derived is efficient in approximating Duffing oscillators. The phase plots generated equally show that the method is computationally reliable in simulating Duffing oscillators. The paper went further to analyze some properties of the method. The outcome of the analysis show that the method derived is consistent, convergent and zero-stable.

Key words: Approximation, Cubic Stiffness, Damping, Duffing Oscillator, Oscillation, Simulation
