| Abstract: | Aiming at the deceleration components of a obturator piston of shoulder launched weapon, this paper gives a 2D axis symmetrical mechanical model. The numerical simulation was made by using finite element analysis method.Based on the analysis and comparison of piston's mechanical properties under different loading velocity,the displacement and stress response were obtained for optimizing the weight of shoulder launched weapon. |
