摘　　要：指出了破片侵彻试验中所用破片质量的变化趋势,详细介绍了3种新型破片发射装置;从弹托的制作材料、无差别分瓣式设计、空气动力学弹托分离技术和拦截弹托分离技术4个方面分析阐述了弹托设计与分离技术;比较说明了吸能、弹道极限V50和比吸能等抗破片性能表征指标在实际应用中的情况;展望了防护材料抗破片性能试验模拟表征技术的发展方向。The trend of projectile mass used in projectile penetration test is pointed. Three new types of projectile-launching devices are introduced in details. Sabot design and separation techniques are analyzed and expounded in terms of sabot materials, undifferentiated split type design, aerodynamics separation techniques and block separation techniques . Different characterization indicators of anti-projectile perform- ance, such as energy absorption , ballistic limit VS0 and specific energy absorption are compared and ex- plained according to their practical application conditions. The development trends of anti-projectile per- formance simulation and characterization technology for protective material are predicted.
