摘要

针对串联攻坚弹前级战斗部爆炸时,后级引信会承受过载和冲击波超压场双重环境的作用和影响,提出基于过载-超压耦合法的后级引信结构强度计算方法。该方法通过建立后级引信的过载超压耦合有限元模型,并施加过载-超压耦合载荷计算后级引信结构件的应力、应变,分析和校核引信的结构强度。试验结果表明:基于过载-超压耦合法的仿真分析结果与靶场试验结果相近,该方法可用于后级引信结构强度的设计和校核.

Abstract

In view of that following fuze is bound to undergo coupled overload-overpressure condition of precursory detonation, structural strength computation of following fuze based on coupled overload-overpressure method was put forward. The coupled overload-overpressure finite model of following fuze was built firstly, and coupled overload-overpressure loads were applied to calculate stress and strain of following fuze body to analyze the structure strength. The field experiment results show that the simulation results of coupled overload-overpressure method are close to that of field experiment and the method could be applied to structure strength calculation of following fuze.
