The folded core sandwich panel, as an advanced sandwich composite structure, is a new type sandwich structure and has a lot of advantages. In this paper, a finite element model of the folded core with imperfections is set up to study the relation between the energy absorption coefficient and the geometric characteristics of M-type folded core. The result of the dynamic compression test simulation agrees well with the experimental result in the CELPACT program. When compared with the ability of honeycomb core, the folded core shows great advantages in energy absorption ability. The energy absorption coefficient of the folded core is more than twice the coefficient of the honeycomb core. The relations between the energy absorption ability and the geometric characteristics of M-type folded core are studied with the help of the response surface method. Finally, an optimization based on the Latin hypercube sampling(LHS) and multi-objective non-dominated sorting genetic algorithm(NSGA-Ⅱ) is proceeded to obtain the folded core with the best energy absorption ability.
