为提高爆炸反应装甲对长杆动能弹的防护能力,应用LS-DYNA仿真软件,结合正交优化设计方法,对爆炸反应装甲的结构进行正交优化设计研究。结果显示:着弹角θ是影响穿深P的主要因素,其次是面板hf,影响最小的是反应装甲与主装甲距离H;权衡空间因素,最佳设计参数θ=60°、hf=4 mm、hb=2 mm、H=10 mm。在此参数组合下,剩余穿深P下降80%左右,侵彻行程W下降79%左右,质量增益系数FWG高达2.54,数值计算的结果和实际结果基本一致,为爆炸反应装甲的设计研究者提供一定的参考和研究方法。
In order to improve the protective capability of explosive reactive armor on long-rod kinetic energy bomb, LS-DYNA simulation software and orthogonal optimization design method were used to optimize the structure of explosive reaction armor. The results show that: the firing angle θ is the main factor affecting the penetration depth P, followed by the panel hf, the least influential is the distance between the reaction armor and the main armor H. The optimal design parameters θ = 60 ° and hf = 4 mm , Hb = 2 mm, H = 10 mm. Under this combination of parameters, the residual penetration depth P decreases by about 80%, the penetration stroke W decreases by about 79% and the mass gain coefficient FWG reaches as high as 2.54. The numerical results are basically in line with the actual results and provide the design researchers with explosive reaction armor Certain reference and research methods.
