This paper presents a detailed analysis of finding the periodic solutions for the high order Duffing equation x(2n)+ g(x) = e(t) (n ≥ 1). Firstly, we give a constructive proof for the existence of periodic solutions via the homotopy method. Then we establish an efficient and global convergence method to find periodic solutions numerically.
