| 摘 要： | 本文提出了一端起爆的线型聚能装药射流形成的不定常理论模型。根据这一模型,当金属罩在爆轰波作用下的运动速度为已知时,则不论此速度是否是时间或初始位置的函数,都能得到射流形成时的速度,质量和位置等参数。 按照本文模型,Defourneaux.M.的定常射流形成定常模型是一个简单的特例。我们利用本文的模型对等厚度装药的情况进行了计算,并与实验结果比较,两者符合良好。同时计算结果表明,考虑射流形成的不定常因素,可以较好地解释射流头部的质量堆积和射流内部的反向速度梯度等实验现象。本文的模型可以为线型聚能切割索的设计提供较为准确的理论指导。

| Abstract: | A non-steady theory of jet formation for end-initiated linear shaped charge has been proposed. According to this theory, the velocity, mass and position of the jet can he obtained when the liner velocity has been known.The steady theory of jet formation proposed by Detourneaux. M. is a special case of this non-steady theory. The case of charge with constant thickness has been calculated and the results is in good accord with the experimental results.This non-steady theory is a fairly good theoretical tool for the design of linear shaped charge. |
