摘要
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 defensive capacity of explosive reactive armor to long-rod projectile,LS-DYNA numerical simulation and orthogonal optimizing design method were used,and the structure of explosive reactive armor(ERA)was optimized. Results show that the impact angle θ is the main factors influencing the penetration P,followed by the front plate hf and the distance from reactive armor to the main armor H in sequence. Weighing the space factor,the optimum design parameters are θ=60°,hf=4 mm,hb=2 mm,H=10 mm. Under the combined parameters,the residual penetration P falls by about80%,penetration route W falls by about 79%,weight gain factor FWGis as high as 2.54. Numerical results and actual results are basically the same. This paper can provide some references and study methods for explosive reactive armor designers.
