Abstract:In this paper, a general nonlinear Duffing equation is studied by the auxiliary function method, some periodic wave, solitary wave and kink wave solutions, which expressed various functions are obtained.
This paper consists of three parts. The present researching situations and significances of Nonlinear wave equations are introduced in the first part. In the second part, the auxiliary function method is introduced and some exact solutions of the generalized nonlinear Duffing equations are obtained by using the method. The research results of the paper are analyzed in the third part.
Key words: Duffing equation; Auxiliary function method; Jacobi elliptic function; Exact solution; Travelling wave
