摘　　要：设计并组建了一种阵列式光幕靶测试系统,主要用于测试战斗部正常破片的速度以及破片群分布,尤其是小破片群速度及破片群分布。介绍了激光光幕靶的测试原理,利用该光幕靶进行了室外爆炸动态实验测试,并对实验结果进行了分析。结果表明,该光幕靶能够精确测量尺寸为5mm的破片速度及破片群分布。An experimental testing technique with light screens is developed to measure the velocity and distribution of warhead fragments,especially small fragments. The basic theory and main principle of the light screens were discussed, and dynamic experiments were designed and carried out to test the velocity and distribution of warhead fragments by the light screens. Experimental results show that the light screens can accurately measure the velocity and distribution of the warhead fragments with a dimension of 5 mm.
