Combined shock and mine protection based on aluminum alloy parts

This paper considers the use of aluminum alloy parts for combined mine protection armored combat vehicles. The study was concerned with anti-mine shields mounted on an vehicle body model. model made 16 mm armor steel. total mass (without shield) 31.1 kg. An shield gripped between two frames and secured bolts. To eliminate effect soil test results, explosive charges were installed a 70 metal plate. initiated ED-8Zh electrodetonator. TG-50/50 used. A DYTRAN 3200B acceleration sensor at center model, signal measured using experimental system. assess without any energy loss by elastic or plastic deformations, rigid (a steel plate thickness 10 10.7 kg) assessed. finite-element simulation conducted. explosion load parameters studied. simulated actual deflections compared EinScan Pro 2X Plus 3D scanner. speed measured. results showed that annealed Al-Mg alloys, in particular AMg6 alloy, absorb better. Any reduces thus factor 20…25 comparison It shown annealing best provides required physical mechanical characteristics load-bearing shields, it is advisable to shape structurize their porous energy-absorbing elements pressing up 33 MPa, most paste parts, after separate tests part element material specimens try out constructions vehicles different purposes.
