摘　　要：大多数进行的破片飞行规律研究都是针对高密度规则金属破片高初速短距离飞行的,而对低密度非金属破片以及长距离飞行的情况研究较少。文中采用理论分析和试验测试相结合的方法,对低密度非金属球形破片在长距离飞行下的速度衰减规律进行了研究。通过理论分析纠正了计算破片衰减速度的关键参数———破片空气阻力系数的取值;通过试验得到陶瓷球形预置破片的速度衰减情况。试验结果与理论分析对比表明,采用此方法计算出来的衰减速度是符合实际规律的。Most studies on the flight rules of fragments are aimed at high-velocity steel fragments short-distance, while there is less study on low-density non-metallic fragments in long-distance flight. In this paper, theoretical analysis and experimental methods were combined to study the rate of attenuation of low density non-metallic spherical fragments for long-distance flight, through theoretical analysis, the rate of decay fragments key parameters-the air drag coefficient fragments values were corrected; through testing the pre-ceramic spherical fragments of the speed of decay were obtained. Compared with theoretical analysis, the test resuits show that the decay rate using this method calculated is in line with the actual law.
