| Abstract: | To analyze the bullet discarding process of open link chain accurately,its finite element calculation formulas were deduced on the basis of contact theory,and then a new method was proposed.By using the new method and finite element model,the bullet discarding process of a machine gun was calculated.Compared with test results,the relative calculation error is 5.4%,and it shows that the method can determine the force of link chair and bullet.Compared with other common used methods,the method proposed in this paper needs not many assumptions for simplification and can obtain more accurate results.The method can offer a reference for the structure optimization of link chair and feed mechanism in weapon,and it can also guide the stress calculation of interference fit problem. |
