Information × Registration Number 0220U000572, 0118U005443 , R & D reports Title Elaboration of module construction elements of ballistic and anti-mine resistance with ceramic and aluminium alloy base popup.stage_title Head Serhii Shvydkyi, Registration Date 12-03-2020 Organization State organization basic center of the critical technology "Microthec" popup.description2 On the basis of the study of the mechanogenesis of crew injuries in the demolition of a combat armored car on mine-explosive devices, substantiation of partial criteria for the stability of parts of the human body to the action of loads, a system of performance indicators and general technical requirements for a system of passive mine protection and cell protection; mathematical models of processes of functioning of elements of modular structures made of different materials are developed, namely: - mathematical model for numerical solution of explosive loading of a combat armored car, taking into account the parameters of high-speed deformation of material and propagation of shock waves in the environment, using Lagrangian approaches, and also takes into account the effect of the shock wave on objects with complex spatial geometry, is a numerical (mathematical) model of the penetration of hom a fire hammer with a different shape of the head part comparing methods of simulation of the effect of the explosion on protective structures and comparing the effectiveness of approaches to numerical simulation of the hammer punching; a comparison of the effectiveness of ceramic security elements with the use of numerical (mathematical) modeling and a full-scale experiment, the method of studying the efficiency of the energy-absorbing element of the cell structure; structural-parametric researches of elements of modular constructions of increase of ballistic and mine resistance of combat armored vehicles by variation of their geometrical and physical-mechanical parameters were carried out, namely: - parametric synthesis of energy-absorbing element was carried out according to the developed method, - theoretical and experimental study of the character of the formation element, - numerical simulation of the explosive load of modular cellular structures and parametric mechanical testing of materials including specimens of AMg6 alloy that has been subjected to different types of heat treatment; field tests of resistance of protective ceramic elements to the defeat of armor-piercing bullets B-32 small arms of caliber 12.7 mm and 14.5 mm; field tests of the resistance of modular structures to the action of explosive loading, including aluminum alloys of high plasticity (using an orthogonal plan of experiment); development of proposals for increasing the level of mine resistance, due to the technical solutions developed on the example of the armored personnel carrier BTR-4 developed a method for assessing the level of mine resistance of the armored personnel carrier; The program and methods of comparative testing of anti-hail protection elements based on ceramics have been developed for installation on armored personnel carriers BTR-60, BTR-70, BTR-80, BTR-3, BTR-4 and machines based on them.
