Study on the Assessment of Damage level of Explosion Damage Elements against Personnel
Personnel are a critical factor in warfare.The damage effects of three types of damage elements,namely,shock wave,thermal effect and fragments,against personnel,are assessed based on the anti-personnel criterion through numerical simulation,experiment and theoretical computation tools.A damage zone of shockwave overpressure against personnel is delineated,and the relationship between scaled blast distance and personnel damage level is established,resulting in the minimum scaled blast distance of damage to personnel being 8.155 m/kg1/3.The spatial distribution of explosion thermal effect is calculated,and the free-field non-fuel air explosive or thermobaric bombs are not suitable for separate assessment of thermal effect on the personnel killing effect is put forward.The generation process of fragments is numerically simulated to obtain the quality,quantity and velocity of fragments.The simulated results are compared with the theoretically calculated results to assess the damage effect of the specific kinetic energy of fragments to personnel.The conclusions can provide reference for the design of warhead and the protection of battlefield personnel.
