| 目的 研究贫铀合金球对Q235钢靶的侵彻行为，为贫铀合金材料侵彻行为的深入研究以及在战斗部中广泛应用提供支撑。方法 采用Johnson-Cook强度模型和失效模型建立贫铀合金球撞击Q235钢靶的模型，利用Abaqus/explicit模块模拟研究贫铀合金球初速与尺寸对剩余速度、扩孔面积、侵彻深度的影响，并对结果进行分析。结果 通过试验与模拟得到了贫铀合金球的穿靶极限速度，两者结果基本吻合，验证了模型参数的准确性。相同尺寸下，贫铀合金球的剩余速度随初速的增大呈线性增大趋势，穿靶后速度衰减率为14.6%~33.2%。初速为900~1 300 m/s、直径为5~9 mm时，扩孔面积比为1.08~1.286。贫铀合金球的侵彻深度(H)随直径(d)和初速(v)的增大逐渐增大，三者的关系为 。结论 贫铀合金球初速和尺寸是影响侵彻深度的关键因素，但对扩孔直径没有显著影响。 |

| The work aims to study the penetration behavior of depleted uranium alloy balls on Q235 steel targets, to provide support for further study of the penetration behavior of depleted uranium alloy material and its wide application in warhead. An impact model of depleted uranium alloy balls on Q235 steel target was established with a Johnson-Cook strength model and a failure model. The effect of initial velocity and size of depleted uranium alloy balls on residual velocity, ream area and penetration depth was simulated with an Abaqus/explicit module, and the results were analyzed. The ultimate penetration velocity of depleted uranium alloy balls was obtained by experiment and simulation, and the results were basically consistent, which verified the accuracy of the model parameters. It was found that the residual velocity of depleted uranium alloys ball with the same size increased linearly with the increase of initial velocity, and the velocity attenuation rate after penetration was 14.6%~33.2%. When the initial velocity was 900 m/s ~1 300 m/s and the diameter was 5 mm ~9 mm, the reamer area ratio was 1.08~1.286. Penetration depth of depleted uranium alloy balls increased with diameter and velocity gradually, the relationship between penetration depth (H), diameter (d) and initial velocity (v) was . The initial velocity and size of the alloy ball are the key factors affecting the penetration depth, but have no significant effect on the reaming diameter. |
