摘要：
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. © 2019, Editorial Department of Transaction of Beijing Institute of Technology.
