METHOD FOR ASSESSMENT OF DAMAGING EFFECT OF ANTI-PERSONNEL FRAGMENTATION MINES Russian patent published in 2023 - IPC F42B35/00 G01L5/14 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to the field of testing anti-personnel fragmentation mines (hereinafter – AFM) of circular damage with random crushing of a hull and mines with ready-made damaging elements for the efficiency of a damaging effect. In the method for assessment of a damaging effect of such AFM, at the first stage, a circular target environment is created from separate elementary platforms, namely wooden shields with a size of 3.0×2.5 m and a thickness of 25 mm, rows of which are located at a distance of 10, 20, 30, 40, 50, and 60 m from its center. For the circular target environment, a sector of scattering of fragments by up to 60 degrees is provided, AFM is detonated from the center of the circular target environment at a height of 1.5 m from the ground with a direction of scattering of fragments of AFM into the target area. The total number of fragments hitting shields of the target environment and a number of penetration of fragments into wooden shields are determined, a depth of penetration of fragments not penetrated shields is measured. At the second stage, indicators of the damaging effect of AFM fragments are calculated, including a radius of reliable damage – a distance from the detonation point, within which it is possible to hit the target with a probability of at least 90%, a radius of effective damage – a distance from the detonation point, within which it is possible to hit the target with a probability of at least 50%, a radius of damage – a distance from the detonation point, within which it is possible to hit the target with a probability of at least 20%. Specific pulses and specific energies of fragments, the coordinate rule of damage of the tested AFM, that is, a probability of hitting a single target with one fragment of AFM at a given distance from the detonation point, are determined. The numerical rule of the tested AFM, that is, a probability of hitting a single target with two or more fragments of AFM at a given distance from the detonation point, is determined, as well as the reduced area of damage, that is, an area around a target, hitting which the target is disabled with a 100% probability.

EFFECT: increase in the accuracy of initial data necessary for building coordinate and numerical rules of damage to an object under study and calculating indicators of a damaging effect of AFM fragments at various distances from a detonation point, as well as reduction in time and complexity of testing.
