摘　　要：为研究LS-DYNA常用仿真方法计算杀爆战斗部破片飞散参量结果的准确性,静爆选取圆筒壳体装药结构和预制破片壳体装药结构,动爆选取预制破片壳体装药结构,对比分析不同的装药算法对计算结果的影响。结果表明,动、静爆时,装药Lagrange算法均优于ALE算法;静爆时,圆筒装药结构的铜壳膨胀速度的相对误差不超过3.02%,预制破片壳体装药结构的破片初速、方向角的平均相对误差为2.62%、16.12%;动爆时,空气域跟随战斗部运动的计算结果较优,其破片初速和方向角的平均相对误差不超过3%、15%。综合计算精度和计算时间,装药采用Lagrange算法较适用于动、静爆破片飞散参量的研究,对破片初速、方向角的计算具有指导意义。In order to study the accuracy of the results by LS-DYNA simulation methods,the cylinder shell charge structure and the prefabricated fragment shell charge structure were selected for static explosion,and the prefabricated fragment shell charge structure was selected for dynamic explosion,the effects of different algorithms on the results were compared and analyzed.The results show that the charge uses Lagrange algorithm is better than ALE algorithm in dynamic and static explosion.During static explosion,the relative error of the copper shell expansion velocity of the cylinder charge structure are less than 3.02%,and the average relative errors of the fragment initial velocity and direction angle of the prefabricated fragment shell charge structure are 2.62%and 16.12%.During dynamic explosion,the result of air domain motion is better,the average relative errors of fragment initial velocity and direction angle are less than 3%and 15%.Considering the calculation accuracy and calculation time,the Lagrange algorithm is more suitable for dynamic and static fragment dispersion parameter study.
