钢板侵彻下电雷管损伤特性的数值模拟
Simulation on damage property of electric detonator under steel penetration
摘要
Abstract
Initiators function as the starting unit of ammunition,and thus their reliability is crucial to the combat efficiency of the weapon system.ANSYS/LS-DYNA numerical calculation software is used to study the damage characteristics of a certain type of electric detonators when the bullets impact on the steel target plates.The results show that the bullet is subjected to an overload acceleration of 230 000 g and 45 μs during the impact,leading to the relative motion of the electric detonator components;the shell suffers a large stress and the maximum compression rate of the grain is about 2.7％;the damage mode of the initiators is the mechanical material damage.The simulation results are instructive to the damage characteristics and structural protection research of the electric detonators.关键词
