Title Research on lateral effect of series structure Abstract Enhanced lateral effect Penetrator (Penetrator with Enhanced Lateral Effect, PELE), is a set of armor-piercing and fragmentation damage function in one of the new penetrator, including housing and pits two parts. Housing made of high-density material, such as tungsten alloy, is mainly responsible for penetration and generate action after fragment penetrating target; elastic core made of low-density material, such as nylon or the like polyethylene. PELE mechanism is: when in contact with the target PELE, since the housing penetration capability than the pits strong Penetrating Target faster than the bomb core is relatively slow, the target plate by a pressing force in the housing and Targets between the expansion of the housing radial high pressure, this time under the action of radial pressure housing and Target force balance when the projectile penetrates the target plate, the balance disappears, the role of housing in the radial force under rupture generated fragments. PELE tandem warhead structure is two or more stages in series single PELE projectile, effective multi-target penetration. In this paper, with theoretical calculation and simulation analysis, the combination of series with two levels of penetration penetration of two layers of target, explore the role of PELE, principle and target velocity, the core material, diameter ratio, ratio of length to diameter and shell material on the influence law of, and it is concluded that the best parameter range, lays the foundation for practical engineering application.
Keywords: the transverse effect; in series; multi layer target; projectile target parameter.
