摘要
采用数值模拟与实验相结合的方法,研究了活性材料增强侵彻膨胀弹（PELE）对金属靶板的作用效应,获得了活性材料增强PELE长径比、靶厚、着速对作用效应的影响。结果表明,改变长径比,对活性材料增强PELE的横向增强效应以及爆燃效应影响不大,但长径比过小,产生的破片数量和活性材料装填量较少,会导致毁伤效果降低;在800 m/s着速下,活性材料增强PELE对10~15 mm厚度范围内的钢靶板毁伤效应较好,更适合应用于拦截高速来袭目标。
The numerical simulation and the experiment of the effects of the enhanced PELE of reactive materials on a metal plate are carried out to investigate the influence of the ratio of length to diameter, the thickness of the plate and the impact velocity on the terminal effects. It is shown that the influence of the ratio of length to diameter on the lateral efficiency and the deflagration efficiency of the enhanced PELE of reactive materials is limited, but the damage effect will decline if the ratio of length to diameter is too small, With the speed of 800 m/s, the damage effect of the enhanced PELE of reactive materials on the plate in a range of 10-15 mm is better; The enhanced PELE of reactive materials performs better for intercepting a high speed target.
