摘要： 为了对助推钻地弹侵彻混凝土的过程有更加深刻的认识，并为设计助推钻地弹选择合适的助推方案，基于经典的空腔膨胀解析模型，考虑侵彻过程中弹丸加速度对侵彻阻力的影响，参考文献［7］给出的Forrestal阻力修正模型，求得他们研究中忽略的对阻力有影响的加速度项，提出了一种能够适用于助推钻地弹的侵彻混凝土半经验阻力计算公式。结合某助推钻地弹的研究工作，对助推钻地弹侵彻混凝土的过程进行了计算为了对助推钻地弹侵彻混凝土的过程有更加深刻的认识，并为设计助推钻地弹选择合适的助推方案，基于经典的空腔膨胀解析模型，考虑侵彻过程中弹丸加速度对侵彻阻力的影响，参考文献［7］给出的Forrestal阻力修正模型，求得他们研究中忽略的对阻力有影响的加速度项，提出了一种能够适用于助推钻地弹的侵彻混凝土半经验阻力计算公式。结合某助推钻地弹的研究工作，对助推钻地弹侵彻混凝土的过程进行了计算通过与试验数据进行比较，得出此种新的半经验侵彻阻力公式能够较好地反映助推钻地弹侵彻过程中所受的阻力。通过对各种助推方案的计算，得出了选择助推方案的一般原则，为助推钻地弹的研究提供了指导。

Abstract: The penetration process of the earth penetration weapon (EPW) with booster into concrete targets was studied to have a deeper cognition for it, and an appropriate boosting scheme was chosen in the design of EPW. Referred to the modified Forrestal resistance model given by Ref.［7］, based on the cavity-expansion theory and considered the influences of projectile acceleration on the penetration resistance, an semi-empirical calculation formula of penetration resistance which could be used for EPW with booster was proposed. Then, in the study on EPW with booster, the penetration process into concrete targets was calculated. Compared with the experiment results, the calculation results show that the new semi-empirical formula can reflect the penetration resistance better. The research in this paper has some practicability; moreover, it can be used to guide the study of the EPW with booster.
