| 摘 要： | 为了研究激光与靶材相互作用过程中存在的冲量传递问题,采用悬摆法和光电测速法相结合的测量方法,用于激光支持爆轰波对靶冲量耦合作用的实验测试研究.在考虑空气浮力、阻力、线重等因素后,建立合理的空气阻力模型,并根据功能原理和转动定理,得到了符合实际情况的悬摆运动方程,进而通过实验验证了摆运动方程的正确性.结果表明,该测试方法所得实验结果与BASS和CAI给出的实验结果基本一致.

| Abstract: | Based on the impulse coupling process between laser and target, a new method of combining pendulum with light electric tachometer was presented,which was adopted in the experiment of impulse coupling between laser supported detonation wave and aluminum target. Considering the air buoyancy, air friction and the pendulum line weight, the actual kinetic equation of pendulum was deduced from the principle of work and power and the rotation theory when the reasonable model of air friction was found. Furthermore, the precision of the kinetic equation of pendulum was checked. Finally, after comparison, the experimental result with the new methodwas in agreement with the experimental result from other methods. |
