The ABC energy of 퐺 is the sum of absolute values of the eigenvalues of ABC (퐺), that is EABC(퐺) =∑|λi|. In this paper, the ABC characteristic polynomials of 𝑃푛,푆푛,퐾푛,퐾푚,푛 퐹푛,퐷4푛 are analyzed by using the defination 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 𝑃푛,푆푛,퐾푛 after deleting an edge is given.
