Abstract
A method for the calculation of dynamic characteristics of bullet-fuze system, based on finite element analysis, is presented. The couple structure between bullet and fuze is meshed by pretension element. The change of dynamic characteristics of bullet-fuze system is simulated in various pretightening force conditions. Both the numerical simulations and the actual hammer tests of a bullet-fuze system are carried out with the same input. The result shows the calculation accuracy of finite element analysis is high.
