摘　　要：为了研究不同材料预制破片的毁伤性能,利用LS-DYNA软件采用对比研究法对钢、钨及陶瓷三种材料预制破片的飞散过程进行了模拟仿真,得到三种材料预制破片的飞散特性。研究结果表明:陶瓷破片初速最大,钢破片次之,钨破片最小,三种材料均具有良好的飞散特性。In order to study the damage performance of prefabricated fragments of different materials,LS-DYNA software was used to simulate the scattering process of prefabricated fragments made of steel,tungsten and ceramic by using comparative research method,and the scattering characteristics of prefabricated fragments of three kinds of materials were obtained.The results show that the initial velocity of ceramic fragments is the largest,that of steel fragments is the second,and that of tungsten fragments is the smallest.The three materials all have good scattering characteristics.
