摘　　要：为提高聚能射流对轻装甲的侵彻能力,提出圆筒形辅助药型罩装药结构,并对其开展优化设计。以影响射流成型的4个因素建立正交优化设计方案,运用非线性动力学仿真软件Autodyn,对射流成型及侵彻靶板过程进行数值模拟。结果表明:当所研究结构的圆筒罩高度h_(1)=40 mm,圆筒罩外径d=30 mm,半球罩与圆筒罩壁厚δ=1.4 mm,装药密度ρ=1.80 g/cm^(3),炸高Z=4D_(1),射流的头部速度与有效长度较高,对间隔靶板的侵彻性能较好。研究结果可为新型聚能装药设计及应用提供技术支持。In order to improve the penetration ability of the shaped energy jet to the light armor, a cylindrical auxiliary charge-type liner charge structure was proposed and optimized design was carried out. The orthogonal optimization design scheme was established based on the four factors that affect the jet forming, and the nonlinear dynamics simulation software Autodyn was used to numerically simulate the process of jet forming and penetration into the target plate. The results show thatwhen the height of the cylindrical liner of the studied structure is h_(1)=40 mm, the outer diameter of the cylindrical liner is d=30 mm, the wall thickness of the hemispherical liner and the cylindrical liner is δ=1.4 mm, the charge density ρ=1.80 g/cm^(3), and the explosive height Z =4D_(1), the head speed and effective length of the jet are higher, and the penetration performance of the spaced target plate is better. The research results can provide technical support for the design and application of new shaped charge.
