| 摘 要： | 以Behrmann和J.Carleone改进的PER理论为基础,通过P.J.Chou方法建立综合考虑药型罩、炸药、壳体等因素的压垮速度计算方法,对药型罩微元的压跨过程、射流头部参数(质量和速度)等进行修正,在此基础上建立Lagrangian坐标系下的射流空间运动方程,编制了相应的计算程序.与数值模拟结果的对比表明, 所建立的射流理论分析方法能有效计算射流参数,可为聚能装药结构设计提供参考.

| Abstract: | Based on modified P-E-R theory founded by Behrmann and J.Carleone,collapse process of liner element and calculation of jet tip parameters including mass and velocity were illustrated.The modified P-E-R theory got collapse velocity of liner elements with simple model provided by P.J.Chou who takes influence of liner,charge,case into account when calculating liner-collapsed velocity.The equations of modified P-E-R theory of shaped charge can be solved with liner-collapsed velocity.Jet motion equations were fo... |
