| Popis: | In order to study the penetration performance of image homing rocket projectile in steel plate-concrete targets, firstly, according to the characteristics of projectile and target, the material constitutive models and state equation were constructed, numerical models were built and the penetration was simulated with the software of LS-DYNA. Then, on the basis of verifying the accuracy of penetration simulation models, penetrations in two typical steel plate-concrete targets were simulated under the conditions of different slant angles. The simulation results show that the rockets can penetrate through the steel plate-concrete targets. Meanwhile, the force, velocity and penetration performance of the projectile were greatly affected by the steel plate in the process of penetration, and the impact, collapse and pit opening effect on the concrete covered by the steel plate were not obvious. In a word, the image homing rocket projectile has good penetration performance in steel plate-concrete targets, which can meet the tactical and technical requirements. |
