摘要/Abstract

摘要： 针对钽材料在多模战斗部中的应用问题，开展爆轰驱动钽药型罩形成双模毁伤元可行性研究。利用霍普金森压杆试验测试钽材料动力学性能，采用LS-DYNA有限元软件仿真研究钽药型罩结构参数（锥角、曲率半径、壁厚）对双模毁伤元(爆炸成型弹丸和聚能杆式侵彻体)成型的影响规律，找出了双模毁伤元成型较好的参数取值范围：锥角140°~150°，圆弧半径0.45~0.55倍装药口径，壁厚0.02~0.024倍装药口径；结合正交设计确定了钽药型罩战斗部最佳结构参数组合，并进行了X光成像试验。研究结果表明：成像试验结果与仿真结果吻合较好，误差均控制在15%之内；与紫铜药型罩相比，钽爆炸成型弹丸毁伤元实际侵彻深度提高55.4%，验证了钽适宜作为多模战斗部的药型罩材料。

Abstract: Based on the problems of tantalum materials in the application of multi-mode warhead, the feasibility study on the formation of dual-mode damage element by detonation-driven tantalum liner is conducted. The dynamic properties of tantalum materials were tested by Hopkinson bar test. The effects of tantalum liner structure parameters (cone angle, radius of curvature and wall thickness) on the formation of EFP and JPC are studied by LS-DYNA finite element software. It is found out that the range of each parameters of optimum dual mode damage element for the formation of the cone angle is 140°-150°, the radius of the arc is 0.45-0.55 times of charge diameter, and the wall thickness is 0.02-0.024 times of charge diameter. The optimum structure parameters of the tantalum liner warhead are determined by the orthogonal design, and X-ray imaging test is carried out. The experimental results are in good agreement with the simulation results, the error are controlled in 15%, and the actual penetration depth is raised to 55.4% compared to Cu. It is proved that Ta is suitable for the liner of multi-mode warhead. Key
