    Abstract
  • In this study, we used the ANSYS/LS-DYNA software to simulate the fall test of the cabin warhead in order to predict its safety performance, and obtained the structural stress deformation and charge overload response of the combat simulation of the warhead in different states.The results show that the stress and overload of the shell and the main charge are the smallest when the cabin warhead is tilted at 45°, but the deformation of the shell is the most severe; and the stress of the shell is small when the large part of the warhead is dropped vertically, but the stress and overload of the charge are the largest, indicating the worst assessment posture.The actual fall test of the large warhead in cabin is successfully passed, and the numerical simulation can provide theoretical support.
