摘要
为实现串联战斗部级间隔爆体结构减重,利用有限元分析软件LS-DYNA建立了某型前级战斗部与隔爆体的数值仿真模型,采用正交试验的方法,研究级间锥形隔爆体前锥角,倒角与前后锥角差值对隔爆体质量的影响规律。结果表明:隔爆体的前锥角对隔爆体质量影响显著,前后锥角差次之,倒角影响较弱。利用正交优化方法,设计三因素四水平的正交优化方案,结果表明当,r=9.9 mm,时,隔爆体的质量最低为485.40 g。研究成果可为串联战斗部隔爆体的结构设计和优化提供指导。
In order to realize the weight reduction of the interspaced explosion-proof body structure at the tandem warhead,the numerical simulation model of a certain type of front warhead and explosion-proof body is established by using the finite element analysis software LS-DYNA.The influence of the front cone angle,the chamfer angle,and the angle difference between front and rear cones on the massof explosion-proof body is studied by orthogonal test.The results show that the front cone angle of explosion-proof body has a significant effect on the mass of explosion-proof body,followed by the angle difference between front and rear cones,and the chamfer angle has a weak effect.Using orthogonal optimization method,the orthogonal optimization scheme of three factors and four levels is designed.The results show that when 2β=115°,r=9.9 mm,β-γ=1.1°,the mass of explosion-proof body is the lowest,which is 485.40 g.This study can provide guidance for the structural design and optimization of series warhead explosion-proof body.
