本文提供的计算方法,可以计算药型罩压垮,射流形成及破甲过程的各种参数。计算模型具有的特点:压垮速度计算采用圆管模型提供的结果;射流速度分布按双线性处理,破甲过程采用解析法计算,并考虑了靶板强度及射流断裂的影响。根据对各种战斗部聚能装药的计算表明,理论结果与实验结果符合较好。本方法可以用于预报聚能装药的射流参数及破甲性能,也可以用来分析各种装药参数对破甲威力的影响。
This article provides computational methods to calculate various parameters of drug overcladding, jet formation, and armor piercing. The model has the following characteristics: the calculation of the collapse speed is based on the results provided by the pipe model; the distribution of the jet velocity is bilinear; the penetration process is calculated by analytical method; and the influence of target plate strength and jet fracture is taken into account. According to the calculated charge of various charge of warhead, the theoretical result is in good agreement with the experimental result. The method can be used to predict the jet parameters and penetration performance of the shaped charge, and can also be used to analyze the influence of various charge parameters on the deterrent power.
