摘要(Abstract)：

利用流体对刚性壁面斜冲击的研究方法 ,对一端起爆的圆形罩线形聚能装药进行了分析。参照经典射流理论 ,对楔形和圆形罩两种线形聚能装药在射流形成的机理上作了对比。对比结果表明 ,楔形和圆形罩线形聚能装药两者各有优劣。此外 ,通过试验 ,对两种药形罩的切割效果进行了比较。从试验结果可以看到 ,在本研究确定的试验条件下 ,圆形罩优于楔形罩。
Using the research method of which a fluid impacts obliquely on a rigid wall,the circular cover end-initiated linear charge was studied.Referring to the classical jet theory,wedge-shaped cover linear charge was contrasted with circular cover linear charge in the mechanism of jet formation.The contrasting result shows that both wedge-shaped cover and circular cover have themselves strong and weak points.In addition,a comparison between the cutting effects of two kinds of linear charge was made through testing.It can be seen from testing results that the circular cover has an advantage over wedge-shaped cover under testing conditions determined in the present study.
