装填材料密度对侵彻膨胀弹终点效应的影响
Influence of Filling Material Density on Terminal Effect of PELE Projectile
摘要
Abstract
By building the model of the penetrator with enhanced lateral efficiency(PELE) and target of steel plate, LS-DYNA was used to simulate penetration of PELE filled copper, 2024-T3 aluminium and nylon against 4340 steel plate at the impact velocity of 1 500 m/s. The results show that the filling material has important influence on the producing of lateral efficiency. In a certain range, with the filling material density decreases, the lateral efficiency range becomes wider, and the remnant velocity after penetrating target becomes lesser.关键词
