  • In this study, the influence of bulkhead perforation structure caused by half armor piercing warhead on the cabin burst effect is studied.LS-DYNA finite element software is used to simulate the internal explosion test of the small ship cabin with the help of reasonable material constitutive relation, equation of state, and the failure criterion at the connection between the material and the structure.The effectiveness of the model is verified by comparing the calculated peak value of shock wave in cabin with corresponding experimental data.By establishing different sizes of bullet holes, the influence of bullet hole size on cabin explosion effect is analyzed.It is concluded that peak value of shock wave overpressure decreases and the peak time of shock wave overpressure is delayed.When the diameter of the bullet hole is less than 1/10 of the bulkhead, the impact of the missile on the chamber explosion effect is negligible.
