摘要

摘要: 对于水泥砂浆的抗弹性能研究，目前很少考虑靶体所处的应力状态，为此基于自研的真三轴静载混凝土侵彻实验装置和水泥砂浆抗弹性能实验结果，讨论了水泥砂浆在不同应力状态下的开坑深度和开坑阻力。应用侵彻深度的经验公式和基于HJC模型的有限元数值计算方法，对比分析了水泥砂浆侵彻实验，结果表明，对于低速冲击过程，采用UMIST公式和HJC模型的数值分析对开坑深度的预测较为有效。应力状态对开坑深度有明显的影响，即随着侧限增加，水泥砂浆的三轴强度提高，弹丸的开坑深度减小。应用基于HJC模型的数值分析方法，研究了弹丸开坑过程中弹体内的加速度波形和y轴支撑杆上的波形，结果表明：弹丸开坑过程对两种波形都有影响，其中y轴支撑杆上的波形可以更好地反映开坑过程。虽然数值模拟结果与实验波形的趋势基本一致，但是应力幅值有一定的差异，说明基于HJC模型的数值分析对开坑阻力的计算能力尚待提高。

Abstract: The stress state of the target was seldom taken into account in the investigation of the ballistic performance of cement mortar. Based on the self-developed penetration experimental system of concrete under true-triaxial confinement and the experimental results of the anti-bullet performance of cement mortar, the depth and resistance of opening pit under different stress states were discussed in the present paper. The empirical formula of penetration depth and finite element method (FEM) based on HJC model were used to analyze the penetration behaviors of cement mortar results. The results showed that under the lower velocity impact, the UMIST formula and the HJC model were both effective in the prediction of pit depth. At the same time, the stress state had an obvious influence on pit depth. With the increase of the lateral limit, the cement mortar strength increases and the pit depth of the projectile decreases. The acceleration wave in bullet and the wave in the y-axis support rod were calculated by FEM based on HJC model. The results showed that the process of projectile opening pit would be recorded by these two waveforms, and the wave structure in the y-axis support rod would be more significantly. Although the tendency of the simulation results was basically consistent with the experimental waves, there was difference in the stress amplitude to some degree, which also indicated that the calculation method of the pit opening resistance based on HJC model needed to be improved.
