摘　　要：为了解决破片毁伤求解采用传统蒙特卡洛算法时效率不高的问题,针对破片战斗部打击地面目标的毁伤规律认知及快速评估需求,提出了先计算并处理破片地面威力场及毁伤参数,后结合相关毁伤判据进行人员毁伤评估的方法。在考虑重力的破片飞散模型基础上,通过分析验证了重力在模型计算中的必要性;通过计算地面威力场分布,探讨了破片初始动能、战斗部飞散角和落角等多个因素对地面威力场的影响规律;通过大破片量模拟,统计得到关键毁伤参数,构建地面人员毁伤矩阵模型,并结合蒙特卡洛算法进行了模型有效性验证。结果表明:在战斗部落角为30°和60°时,利用参数统计法得到的毁伤矩阵模型能有效预测人员毁伤概率,计算结果与蒙特卡洛方法结果的差异不超过0.1。Aiming at the low solution efficiency of fragment damage by Monte Carlo algorithm,evaluation method for warheads fragments against ground targets was proposed with the consideration of the cognition of the damage law and the requirement of rapid assessment.Firstly,power fields and damage parameters of the fragment ground were calculated and processed.Then,the personnel damage was evaluated based on relevant damage criteria.Additionally,the necessity of gravity in the calculation of the proposed model was analyzed and verified based on a fragment dispersion model considering the gravity.Then,the ground power field distribution was calculated to explore the influence law of initial kinetic energy of the fragment and the dispersion angle and the falling angle of the warhead on the ground power field.Furthermore,key damage parameters were statistically analyzed through large-scale fragment simulation.Accordingly,a ground personnel damage matrix model was constructed.Finally,the proposed model was verified by Monte Carlo algorithm.Results showed that the damage matrix model obtained by the proposed method can effectively predict the damage probability when the warhead falling angles are 30°and 60°and the computaional probability difference is no more than 0.1.
