Abstract

To explore the effect of head shape on the penetration capability of a fragment simulation projectile (FSP), single-stage kinetic energy penetration FSP with different head shapes was taken as the research object. The ballistic limit velocity (BLV) is used as the evaluation index in the study of experiments and numerical simulations. The nonlinear dynamic analysis finite element software LS-DYNA with the Lagrange algorithm is used in the simulation for FSP from 35CrMnSi steel penetrating target plates from 10CrNi3MoV (921A) steel of various thicknesses (3, 5, 8, and 10 mm). The ballistic experiment corresponding to the numerical simulation has been designed and carried out to verify the effectiveness of the numerical results. The results show that the values of BLV obtained through numerical simulation and ballistic experiment coincide well, and the average relative error in both is 7.14%. The research results provide a reference for designing FSPs and engineering applications of fragmentation kill warheads.

弹头形状对碎片模拟弹丸穿透能力的影响
为探索弹头形状对破片模拟弹丸(FSP)穿透能力的影响,以不同弹头形状的单级动能穿透 FSP 为研究对象。在实验和数值模拟研究中,采用弹道极限速度(BLV)作为评价指标。在模拟 35CrMnSi 钢击穿不同厚度(3、5、8 和 10 毫米)10CrNi3MoV(921A)钢靶板的 FSP 时,使用了带有拉格朗日算法的非线性动态分析有限元软件 LS-DYNA。为了验证数值模拟结果的有效性,设计并进行了与数值模拟相对应的弹道实验。结果表明,数值模拟和弹道实验所获得的 BLV 值吻合良好,两者的平均相对误差为 7.14%。研究成果为破片杀伤弹头的FSP设计和工程应用提供了参考。

期刊介绍: Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
