This paper proposes an improved method for approximating the frequency of the cubic-quintic Duffing oscillator by using a weighted average amplitude-frequency relation.
This paper proposes an amplitude-frequency relation which improves He's simple, one-step, approach for approximating the frequency in the case of the cubic-quintic Duffing oscillator; the relation we apply is a weighted average amplitude-frequency relation.
