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.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.
