Structural Optimization of Liner based on Weighted Gray Correlation Analysis

为研究圆锥形药型罩的锥角、锥径、壁厚3个参数对聚能射流效果的影响程度并优化药型罩结构,设计三因素四水平的正交试验,采用ABAQUS软件对聚能射流破甲进行仿真模拟,利用赋权灰色关联法分析射流破甲正交试验结果,得到药型罩的锥角、锥径、壁厚与射流破甲效果的关联度。结果表明:锥角对聚能射流破甲效果影响最大,锥径、壁厚的影响次之。最佳聚能射流破甲效果的药型罩参数组合为:圆锥角61.2°、圆锥半径18 mm、壁厚1.05 mm。最佳参数组合下,聚能金属射流最大速度为5855 m∙s^(-1),侵彻靶板深度为59.43 mm,侵彻靶板开口直径为8.24 mm。研究结果可为聚能射流的侵彻应用提供相关理论指导。

In order to study the influence of degree of cone angle,cone diameter and thickness of conical liner on shaped charge jet effect and optimize the structure of liner,orthogonal test with three factors and four levels was designed.ABAQUS software was used to simulate the shaped charge jet to penetrate the target,and weighted gray correlation method was used to analyze the orthogonal test results of jet target penetrating.The correlation degree between the angle,diameter and thickness of the car⁃tridge and the effect of jet target penetrating was obtained.The results show that the cone angle has the greatest effect on shaped charge jet,and the cone diameter and thickness have the secondary effect.The parameter combination of liner for the best shaped charge jet target penetrating is:cone angle 61.2°,cone radius 18 mm,thickness 1.05 mm.Using the best combination of parameters,the maximum velocity of the shaped charge jet is 5855 m·s^(-1),the depth of the penetrating target is 59.43 mm,and the opening diameter of the penetrating target is 8.24 mm.The research results can provide theoretical guidance for the appli⁃cation of shaped charge jet penetration.
