摘要
提出一种基于有限元分析的弹引系统动态特性计算方法.采用预紧单元对弹体和引信的耦合部位进行网格划分,对不同拧紧力时弹引系统的动态特性进行模拟.在相同的激励环境下,对某弹引系统进行了有限元数值计算和实测锤击试验,试验结果表明,所采用的有限元分析方法精度较高.
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.
