Used the LS-DYNA procedure to set up numerical model on penetration of semi-infinite aluminum-alloy targets by tungsten-alloy rod over a wide velocity range has been discussed. The mass of penetrator is about 46.7 g with a length over diameter ratio of 15. Based on experiment results from the reference, distinguished analytical models were used individually in case of relative high impact velocity and low one, and parameters of constitutive equations including failure parameters for aluminum alloy 7020 and tungsten alloy were calibrated. Penetration experiments within the impact velocity from 200 m/s to 2 500 m/s were numerically simulated, and the numerical results were in good agreement with experiments. In addition, the effect of projectile nose to penetration was investigated, and the relationship between length over diameter ratio and penetration was obtained. In the case of high impact velocity, the nose shape has little effect on penetration. Numerical results indicate that dimensionless penetration decreases as length over diameter ratio increases.

使用LS-DYNA程序对钨合金杆侵彻半无限厚铝合金靶问题进行了数值模拟研究,参考文献中的实验数据,分别建立了在低着速与高着速情况下所适用的计算模型,标定了材料参数,计算了撞击速度从200 m/s到2 500 m/s范围内的侵彻情况,计算结果与实验数据符合较好。同时研究了影响长杆侵彻效能的主要因素,结果表明,在高着速的情况下,杆的头部形状对侵彻深度的影响很小,以杆长无量纲化的侵彻深度(P/L0)随长径比(L0/d)的增大而降低。

使用LS-DYNA程序对钨合金杆侵彻半无限厚铝合金靶问题进行了数值模拟研究,参考文献中的实验数据,分别建立了在低着速与高着速情况下所适用的计算模型,标定了材料参数,计算了撞击速度从200 m/s到2 500 m/s范围内的侵彻情况,计算结果与实验数据符合较好。同时研究了影响长杆侵彻效能的主要因素,结果表明,在高着速的情况下,杆的头部形状对侵彻深度的影响很小,以杆长无量纲化的侵彻深度(P/L0)随长径比(L0/d)的增大而降低。

长杆侵彻  /  数值模型  /  钨合金杆  /  铝合金

Used the LS-DYNA procedure to set up numerical model on penetration of semi-infinite aluminum-alloy targets by tungsten-alloy rod over a wide velocity range has been discussed. The mass of penetrator is about 46.7 g with a length over diameter ratio of 15. Based on experiment results from the reference, distinguished analytical models were used individually in case of relative high impact velocity and low one, and parameters of constitutive equations including failure parameters for aluminum alloy 7020 and tungsten alloy were calibrated. Penetration experiments within the impact velocity from 200 m/s to 2 500 m/s were numerically simulated, and the numerical results were in good agreement with experiments. In addition, the effect of projectile nose to penetration was investigated, and the relationship between length over diameter ratio and penetration was obtained. In the case of high impact velocity, the nose shape has little effect on penetration. Numerical results indicate that dimensionless penetration decreases as length over diameter ratio increases.
