Study of the Impact of Mine Blast on Armored Vehicle Occupants by the Physical Modelling

Abstract

The paper presents the results of a physical modelling of the mine blast through an armored vehicle and dynamic load on occupants obtained on Anthropomorphic Test Device Hybrid III 50th. The modelling experiments were conducted in the underground experimental base of the Mining Institute, specially designed for the study of explosion processes. The model contains four support stands, a bottom plate, an upper plate and extra mass. The plate has the following dimensions: 1920 mm x 790 mm, thickness-8 mm. Hybrid III 50th was installed on the upper plate of the armored vehicle model. The following dynamic characteristics of the dynamic response are recorded in the model: axial compression force (Fz) in the tibia, vertical acceleration (Az) in the pelvis, shear force (Fx), axial compression force (Fz) and flexion bending moment (My) in the neck. The expected injuries of the occupants of the armored vehicle are estimated.
