| 摘 要： | 根据爆炸式反应装甲与长杆体相互作用的物理现象,研究了反应装甲干扰长杆体侵彻主装甲的机理,建立了长杆体与爆炸式反应装甲相互作用的理论模型.采用长杆体斜侵彻半无限靶板的分析模型,计算出杆体对主装甲的侵深和最终行程.实验研究表明,采用本模型计算的侵深和行程与实验结果基本一致.影响反应装甲对长杆体干扰的主要因素有反应装甲厚度、弹着点位置以及杆体直径.

| Abstract: | Based on the physical phenomena of interaction between long-rod penetrator and explosive reactive armor(ERA),the disturbance mechanism of ERA against long-rod penetrator was investigated.An theoretical model for the interaction was established.The depth and distance in main armor caused by long-rod penetrator were caculated by use of the analytical model of long-rod obliquely penetrating semi-infinit targets.The test results show that the calculation results are coincident with that of the tests.The major factors include impacting position of long-rod penetrator against ERA,rod diameter,and thickness of every plate of ERA-front plate,rear plate,and explosive. |
