摘要
文中应用二维拉氏速度光学测量技术,测得两种球缺形药型罩在炸药驱动下内壁给定位置的运动参数变化历程,包括速度和台劳角变化历程,并得出其极限速度、特征加速时间和极限台劳角。比较了壁厚对运动参数的影响,分析了常用极限速度计算方法,讨论并修正了计算结果偏大的问题。
A experimental measuring system of double-illuminator method was used in order to study the history of collapse parameters include two dimensional Lagrange velocity and Taylor angle about two type of spherical liners, The final velocity, final Taylor angle and characteristic time of specified particles on inner wall of liners were measured . By comparison between theoretical and experimental result the conclusion that theoretical result is bigger than experimental was discovered.
