doi:10.12382/bgxb.2024.0838

Abstract

Abstract:

The warhead power is the load input for the calculation of damage effect. The accurate construction of a static power field model for warhead becomes an important task to evaluate the accuracy of damage assessment task. Based on the unique characteristics of natural fragmentation warhead, a method for reconstructing the static power field model for warhead is proposed by numerical simulation, theoretical analysis and experimental verification. That is, an initial model of fragmentation power field is constructed based on the calculated results of the numerical simulation model, an initial model of the shock wave power field is constructed based on the classical analytical theory, and the key characteristic quantities of the power field are corrected item by item based on the sample data of the experiment. Through the case calculation, it is shown that the power field model of natural fragmentation warhead established by using the proposed reconstruction method can accurately describe the actual warhead power characteristics, and can be effectively applied in the related fields of warhead performance evaluation and weapon equipment effectiveness evaluation.

Key words: natural fragmentation, power field reconstruction, static explosive experiment, experimental correction
