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.

Key words： tandem warhead; following fuze; structure strength; coupled overload-overpressure method
