Abstract

Based on the structure of a certain type of dyeing projectile, the mathematical simulation model was established, and the simulation of the shell deformation in Ansys/LS-DYNA software was carried out by using the FEM/SPH method. The explosion process of the shell shell in different time displacement nephogram and the equivalent stress nephogram analysis, the maximum displacement and the maximum equivalent stress. Through the static explosion test, get the maximum deformation of the shell, the test results are in good agreement with the simulation results (the error is only 0.3cm), prove the correctness of the model, provides an important reference for further research on throwing stain.
