| 摘 要： | 为研究激光与靶材相互作用过程中的冲量传递问题,提出了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.在考虑空气的影响后,建立空气阻力模型,并根据流体力学理论,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M.Bass和Xijie Cai给出的实验结果基本一致. |

| Abstract: | Based on the impulse coupling process between laser and target,we presented a new method of combining pendulum with light electric tachometer,which was adopted in the experiment of impulse coupling between laser supported detonation wave and aluminum target.Considering the air friction,the actual kinetic equation of pendulum can be deduced from hydrodynamic theory when the reasonable model of air friction was found.Furthermore,the precision of the kinetic equation of pendulum was checked.Finally,comparing the experimental result from new method with experimental result from other methods,a good agreement was gotten. |
| Keywords: | laser physics impulse coupling between laser and target impulse air friction the kinetic equation of pendulum |
