Analysis and Simulation on Impact Deformation of a Projectile Sabot Based on ABAQUS

摘要

The impact deformation process was researched during the projectile sabot in high speed impinging on the conic-chamber in the interior ballistics phase . The mathematical model of deformation was set up based on special structre of conic-chamber and projectile. The nonlinear dynamic deformation process was simulated based on finite element software ABAQUS. The v-t curve and stress nephogram were obtained. And the simulation results were coinsident with the experimental results. The research can provide references for the designs of conic-chamber and projectile.
