【摘要】 以25mm口径榴弹引信系统为研究对象，采用有限元结构分析软件ADINA进行系统的弹塑性动力分析。计算结果给出了系统内关键部位包括装药的应力历程和最大弹底压力时的应力分布。同时进行了系统的模态试验和靶场试验，利用试验取得的参数修改系统有限元模型以获得准确的有限元分析结果。更多还原

【Abstract】 Dynamic stress analysis of projectile/fuze system is studied making use of the sofeware package ADINA.Stress vs.time relationships,stress distribution of sys-tem parts when under maximum base pressure are given.At the same time,modal analysis and firing tests have been conducted to improve the finite element model of the system.更多还原
