Abstract：The ABC energy of G is the sum of absolute values of the eigenvalues of ABC(G)， that is EABC(G)＝|(n)λi|. In this paper， the ABC characteristic polynomials of Pn、Sn、Kn、Km，n、Fn、Dn(4) are analyzed by using the definition and properties of ABC energy of graphs and combining the structures of several special graphs. The corresponding ABC energy is given， and the change trend of ABC energy of Pn、Sn、Kn after deleting an edge is given.
