为了配合破片战斗部的研制,对靶网法测破片速度进行了改进。用印刷线路板做靶网,使原来的打断靶改成打通靶,并采用高精度多通路计时仪。用这种通靶测速法,对三种型号战斗部的破片速度进行测量,试验结果表明:该方法准确可靠,可与4000～6000幅/秒的高速照相法的结果相比较。该方法可测近距离(0～6米)范围内破片速度和衰减系数。本方法特别适用于中、小型战斗部或破片飞散角小的战斗部。 In order to cooperate with the development of the fragment warhead, the target mesh method rupture speed has been improved. Using printed circuit board to make the target network, so that the original target to break the target to open, and the use of high-precision multi-channel timer. The velocity of fragmenting of the three warheads was measured by this method of passing target velocity test. The experimental results show that the method is accurate and reliable and can be compared with the high speed photographic method of 4000-6000fps. The method can measure the fragment velocity and attenuation coefficient within a short distance (0 ~ 6 meters). This method is especially suitable for medium and small warheads or fragments of the scattering angle of the warhead.
