|
- Using the method of harmonic balance, an approximate solution to the Duffing equation is sought of the form:
with and
Application in the Duffing equation leads to:
Neglecting the superharmonics at the two terms preceding and have to be zero. As a result,
Squaring both equations and adding leads to the amplitude frequency response:
as stated above. (en)
