摘　　要：针对反爆炸反应装甲(ERA)串联爆炸成型弹丸(EFP)成型设计问题,建立串联EFP引爆能力、分离时序和侵彻能力的理论条件。采用ERA引爆判据、EFP速度衰减理论和侵彻理论,分析形状、质量比和速度差对引爆能力、分离时序和侵彻能力影响规律。基于作用场时间τe≤1500μs的典型ERA,在飞行距离H≤1000∅(∅为装药口径)时,获得串联EFP成型特征的必要条件,其中:球-杆组合型,前后EFP直径比d_(f)/d_(r)≤1.09,前EFP质量与总质量之比0.17<m_(f)/m≤0.40,前后EFP速度差Δv≥150 m/s;杆-杆组合型,d f/d r≤1.09,0.20≤m_(f)/m≤0.65,Δ_(v)≥166 m/s.对一种球-杆形串联EFP开展反ERA联动实验,采用高速摄影系统观测得到前后EFP分离飞行、前EFP击爆ERA以及后EFP侵彻靶板过程,验证了该设计方法和必要条件的正确性。The theoretical conditions of detonation capability,separation timing and penetration ability of tandem EFP were proposed for the design of tandem explosively formed projectile(EFP)used for antiexplosive reactive armor(ERA).The ERA detonation criterion,EFP velocity decay theory and penetration theory are used to analyze the influences of shape,mass ratio and velocity gradient on detonation capability,separation timing and penetration ability.For the typical ERA of which interference timeτe is less than or equal to 1500μs,the necessary conditions of the tandem EFP forming characteristics for distance H≤1000∅(∅is charge diameter)are obtained,where 1)for the shape of sphericity-rod combination,the front and rear EFP diameter ratio d_(f)/d_(r)≤1.09,the ratio of front EFP mass to total mass is 0.17<m_(f)/m≤0.40,and the front and rear EFP velocity gradientΔv is larger than or equal to 150 m/s;2)for the shape of rod-rod combination,d f/d r≤1.09,0.20≤m_(f)/m≤0.65,Δv≥166 m/s.An EFP warhead that could form the sphericity-rod tandem EFP was designed and processed.The countering ERA linkage experiment was carried out.The process of EFP separating flight,front EFP detonating ERA,and rear EFP penetrating into target were observed by using the high speed photographic system.The experiments verified the correctness of the theory and the necessary conditions.
