摘要/Abstract

摘要： 为有效毁伤装甲目标，有必要考虑如何尽可能规避爆炸反应装甲作用场。针对爆炸反应装甲和破甲弹结构特性及作用机理，建立一种基于坦克炮低伸弹道的近炸引信作用距离计算模型。根据模型几何关系确定出破甲弹与爆炸反应装甲的极限交会距离，进而推出一级近炸引信作用的合理距离。运用该模型以某型破甲弹为例，推出极限交会距离的理论值以及一级近炸引信作用距离与弹丸速度的关系。爆炸反应装甲威力场试验表明，极限交会距离的安全临界值与其理论计算值基本吻合，由此计算模型推导出的引信作用距离具有较高精度，对工程设计具有一定的指导意义。

Abstract: In order to effectively damage an armored target with explosive reactive armor(ERA)，it is necessary to study how to avoid the explosive field of ERA.A calculation model for the operating range of proximity fuze based on the low trajectory of tank gun is established on account of the structure and action principle of ERA and high explosive antitank (HEAT) projectile. According to the geometrical relationship of the proposed calculation model，the limiting intersection position of HEAT projectile and ERA as well as the proper operating range of the first-stage proximity fuze can be worked out. The theoretically calculated value of limiting position and the relationship between the operating range of the first-stage proximity fuze and the velocity of HEAT projectile were derived by taking a HEAT projectile as an example.Experimental results show that the critical value of limiting intersection position of HEAT projectile and ERA is approximately equal to its theoretically calculated value，and the theoretical value of this calculation model has higher accuracy and has guiding significance for the actual project design.
