摘　　要：针对杀爆战斗部动爆试验破片场毁伤威力考核,为了找出最佳终点弹道参数,采用射击迹线法结合破片运动过程的方法计算了动爆时破片在地面的分布场,统计试验靶板上的破片数目,依据目标毁伤准则,筛选出能够有效毁伤的最远及最近靶板位置,以平滑连接方式将其围成大圈和小圈,两圈内的面积即为有效杀伤面积,计算出等效杀伤半径。通过该计算方法可计算不同终点弹道参数下的等效杀伤半径,并寻优找出最佳终点弹道参数,为战斗部动爆试验提供数据支撑。For the damage power assessment of dynamic explosion test of blast-fragmentation warhead,and in order to find out the optimal terminal ballistic parameters,the fragments projection on the ground was calculated in program by shot-line model and motion process of fragments.The number of fragments on the test target was counted.According to the target damage criterion,the furthest and nearest target position that can be effectively damaged was screened out.So,smoothly connecting the target position,the large and small circles were surrounded.The area within two circles was the effective lethal area.The equivalent lethal radius was calculated.Through this calculation method,the equivalent lethal radius from different terminal ballistic parameters can be calculated.And the optimal terminal ballistic parameters can be found.It provides data support for dynamic explosion test of warhead.
