Establishment and analysis of damage calculation model under fuel air explosion effect

Fuel air explosive has unique damage characteristics because of its different action mechanism. In this paper, through analyzing the damage mechanism and characteristics of fuel air explosive, the damage efficiency of fuel air explosive was quantitatively described by using overpressure and specific impulse. In combination with theoretical calculation and experimental fitting, the corresponding damage effectiveness calculation model of fuel air explosive was established. According to the actual application of fuel air explosive, the group of personnel was selected as the pseudomorphic target, the distribution area and relevant parameters of the target were set, so as to establish the corresponding damage criteria, which provided a reference for the effective evaluation of the damage efficiency of fuel air explosive.
