<p>For the scientific and quantitative assessment of the comprehensive damage power of blast - fragmentation warheads, by considering the attenuation of the shock wave pressure peak and fragment velocity with the increase of the detonation center distance, the variable weight idea is introduced. The comprehensive damage power evaluation model of the blast fragmentation warhead is proposed based on variable weight and criteria importance through intercriteria correlation (CRITIC). The static explosion tests of blast fragmentation warhead with equal volumes of 3,4-Dinitrofurazanylfuroxan (DNTF) and trinitrotoluol (TNT) were carried out, and the power parameters were tested, such as shock wave pressure and fragment velocity, and the variation law of each power parameter is analyzed. Combined with the measured data and the comprehensive power evaluation model proposed in this paper, taking the ground-reflected pressure peak, free field pressure peak, and total pressure peak as the evaluation indexes of shock wave power, respectively, and combining with the fragment velocity, the comprehensive damage power of the DNTF charge blast-fragmentation warhead was evaluated, it is obtained that the maximum TNT equivalent ratios are 1.78, 2.13, and 2.31, and the minimum is 1.57, 1.69, and 1.73. This method can scientifically and objectively calculate the weight of the shock wave and fragment at different distances from the explosion center and can accurately evaluate the comprehensive power of the blast-fragmentation warhead, which can provide an important reference for warhead design.</p>
