| Abstract: | The launching strengths of three structures of the 122mm shrapnel are investigated by means of the three-dimension fin ite element software of “PRSA-2” in this paper. The stress and the shift value of dangerous section of projectile band are also calculated via the calculation of different structures and different case. The iso-stress curves of projectile, the results of the bottom and the body of projectile are given. The data can be referred to the product design accurately and reliably. |
