| 摘 要： | 为了研究非对称性因素对线型聚能射流的影响,运用流体动力学原理,从理论上分别分析和推导了斜入射冲击波和药型罩不对称2个主要因素对射流的影响程度.数值模拟和理论计算均表明:不对称程度较小时,射流不会明显偏离轴线,但射流的两翼将出现不对称,射流的缩颈和断裂时间也会提前;当不对称程度增大时,射流明显偏离轴线,射流的两翼明显不对...

| Abstract: | In order to study the effect of asymmetric factors on linear shaped charge,the fluid dynamics was used,and two major factors such as oblique incident wave and asymmetric liner,were considered by theoretical analysis respectively.Numerical simulation and theoretical calculation show that:when asymmetry is small,the jet dosen ' t significantly deviate from the axis,but the asymmetry of jet ' s wings appears,and the necking time and the fracture time of the jet will be advanced.When asymmetry increases,the jet... |
