摘要

为深入研究冻土靶体的抗侵彻特性，开展了冻土靶体抗侵彻系列模型试验，得到了不同温度下冻土靶体抗尖卵型弹体侵彻成坑效应、弹道轨迹和侵彻深度等参数。试验结果表明，冻土靶体抗侵彻特性与其温度和弹体撞击速度密切相关，冻土温度相同，弹体撞击速度越大，冻土靶体表面成坑越大，抗侵彻深度越大，弹体侵彻速度相近，冻土温度越低冻土靶体表面成坑越小，抗侵彻深度小。为准确预测冻土靶体抗卵形弹体侵彻深度，引入考虑温度效应的摩尔-库伦准则，结合空腔膨胀理论对冻土靶体抗侵彻深度进行计算分析，与试验实测数据对比，理论预测值能够较准确反映冻土靶体抗侵彻深度与冻土温度和弹体侵彻速度间的关系。

Abstract

To study the anti-penetration characteristics of frozen soil targets deeply, model tests on the anti-penetration of frozen soil targets were carried out. We obtained the parameters such as cratering effect, ballistic trajectory and penetration depth of frozen soil targets under the impact of pointed egg-shaped projectiles at different temperatures. The test results show that at the same frozen soil temperature, the greater the impact velocity of the projectile, the larger the crater formed on the surface of the frozen soil target and the greater the depth of anti-penetration. At the similar impact velocity of the projectile, the lower the frozen soil temperature, the smaller the crater formed on the surface of the frozen soil target and the smaller the depth of anti-penetration. To accurately predict the penetration depth of the frozen soil target by the oval-shaped projectile, the Mohr-Coulomb criterion considering the temperature effect was introduced, and the calculation and analysis of the anti-penetration depth of the frozen soil target were carried out based on the cavity expansion theory. By comparing with the measured data from the tests, the theoretical prediction values can reflect the relationship between the anti-penetration depth of the frozen soil target, frozen soil temperature and the impact velocity of the projectile accurately.
