带前舱战斗部对钢筋混凝土侵彻规律研究

为分析在临界穿透速度条件下，着靶参数对某型带前舱战斗部侵彻能力的影响，基于LS-DYNA非线性有限元分析软件，采用实体单元钢筋建模方法，建立了带前舱战斗部侵彻钢筋混凝土目标3维仿真模型，给出了在极限穿靶速度条件下，着靶角度、攻角等参数的变化对战斗部侵彻能力的影响规律，计算结果与实验结果吻合较好.研究结果表明，着靶角度对战斗部侵彻能力影响显著，在极限穿靶速度条件下，一定范围的负攻角有利于战斗部的侵彻. 

Study on the Law of Penetration of Reinforced Concrete by Warhead with Forecabin

In order to analyze the influence of target parameters on a certain type forecabin warhead penetration ability under critical penetrating velocity conditions, nonlinear finite element analysis software LS-DYNA and the reinforced solid element modeling method were adopted to set up the forecabin warhead penetration target 3D simulation model. The influence of the change of parameters, such as target angle and attack angle, on the penetrating ability of warhead at an extreme speed was obtained. The calculation results agreed well with the experimental results. The research results show that target angle has a significant impact on warhead penetration capability, and a certain range of negative attack angle is conducive to the penetration of warhead under the condition of an extreme penetration speed.
