| 摘 要： | 针对测量冲量耦合系数的水平导轨法和冲击摆法，分别进行了误差计算和实验研究。计算结果表明:水平导轨测量法的相对误差（4.6%）略小于冲击摆测量法的相对误差（6.1%），其中位移参数和最大摆角的测量精度对于相对误差的影响最大。实验结果表明:两种方法的测量结果基本一致，冲量耦合系数均随着入射脉冲能量的增大而增大，且两组数据相差在6%以内，在入射脉冲能量为3~14 J时，冲量耦合系数最高可达260 N·MW-1。

| Abstract: | Air track method and impact pendulum method are two common measurement methods of impulse coupling coefficient.Relative errors were calculated and measurement experiments were carried out with the two methods,respectively.The results show that the relative error of air track method(4.6%) is smaller than that of impact pendulum method(6.1%),and measuring errors of the displacement data and the pendulum angle contribute the most to the system error.The experimental results of the two methods are basically ide... |
