云爆超压对火箭车内有生力量毁伤评估研究
Research on damage evaluation model of effective in rocket launcher caused by Fuel-Air-Explosive overpressure effect
【摘要】 为探究云爆弹超压效应对火箭发射车内有生力量的打击效果,基于云爆弹地面威力场实验数据,利用AUTODYN软件计算、探究火箭发射车内的超压分布及规律。通过蒙特卡洛法以及超压杀伤准则,提出云爆超压对火箭发射车内有生力量的毁伤评估方法。结合爆炸相似律,建立相应的毁伤评估模型,分析弹目相对距离对毁伤效果的影响,并基于33 kg云爆弹实验数据进行验证。研究结果表明:火箭发射车内,当其余条件均一致时,跪姿平面车内超压高于坐姿平面,副驾驶区域超压高于主驾驶区域,火力控制室内超压一致。对于160、33 kg云爆弹,分别在28~36.35 m、11.35~15.46 m对车内人员的封锁率由1降为0。毁伤评估模型所得结果与实验分析误差小于2.5%,可供云爆弹的设计者借鉴。
【Abstract】 To explore the overpressure effect of the FAE on the effective in the rocket launcher, based on the ground power field of the FAE experimental data, AUTODYN software was used to calculate and explore the distribution and rule of overpressure in rocket launcher. Based on the Monte Carlo method and the overpressure killing criterion, the damage assessment method of FAE overpressure on the effective in the rocket launcher was put forward. Combined with the explosion similar law, the corresponding damage assessment model was established and verified based on the 33 kg FAE example. The results show that the overpressure in the kneeling plane is higher than that in the sitting plane, the overpressure in the co-driver area is higher than that in the main driving area. the overpressure in the fire control room is same. For charge 160 kg and 33 kg FAE, the blocking rate of the effective in the rocket launcher is reduced from 1 to 0 at 28~36.35 m and 11.35~15.46 m, respectively. The damage assessment method calculated results are basically consistent with the actual data, and the difference is less than 2.5%, which can be used as a reference for the FAE design.
