Were analyzed the characteristics of damaging elements of artillery systems and small arms. Were analyzed the characteristics and structures of personal Armor protection. Modern protection has layered structure. The main blow of high speed sub munitions takes the hard plate. They can be made of metal or high-strength double-layer panels. At a meeting with the panel the toe of bullet was destroyed. As a result of growing area of interaction between the bullet and the panel, there is a deflection and uncoupling ceramic bullet while destruction. When you hit the drummer in the obstacle created several types of wave perturbations that propagate with different velocities. These effects cause is a complex stress state structure, whose intensity decreases rapidly with time. The aim of the article is to investigate the interaction of highstriker with a protective barrier in the form of a set of hollow cylinders. The methods that are used: Improving personal armor protection can be achieved by applying the optimum combination of new materials and advanced structural and circuit design. Character penetration drummer an obstacle may change if the obstacle is to imagine a structure that consists of a set of hollow cylinders. Considered the process of interaction, of high-speed impactor, with a protective barrier, in the form of a set of hollow cylinders. In contact with the surface layer drummer obstacles by having an expanded, drummer enters the hollow cylinder, which closely hugs the side surface of the impactor, creating resistance to motion. When moving drummer in the cylinder is converting kinetic energy into energy impactor cylinder and deformation work to overcome friction. Thus, the energy of drummer extinguished intermediate layer and redistributed to the power frame inner layer. following results are obtained. The proposed a model to determine the depth of penetration drummer an obstacle in the form of a set of hollow cylinders. There are results of the calculations. It is proposed to further improve the protection of personal Armor achieve by applying the optimum combination of new materials and advanced structural and circuit design.
The article is devoted to the aspects of engineering provision of forces for the state border protection, namely the use of a blocking barrier obstacle to block certain areas of the territory in order to prevent a mass transfer of the state border violators at the border checkpoints or during the cessation of massive disturbances in the border areas. It also deals with the determination of the stability of the blocking barrier obstacle in the process of preparing it for its intended purpose in case of preventing the passage or breakthrough of the crowd on the prohibited areas of the territory. Proceeding from the above presented in the article, the state border guard forces were requested to use a new construction of a barrier, namely: a blocking barrier obstacle to which Ukraine's patents for invention were obtained. The peculiarity of the blocking barrier obstacle is that it consists of hollow connecting elements made of light polymer material. To increase the stability of the blocking barrier in case of external hollow loads, the connecting elements are filled with liquid. Sustainability refers to the ability of the structure to withstand the external loads, capable to shift or overturn them, thus ensuring the increase in the efficiency of the task of preventing passage or breakthrough of violators into the prohibited areas of the territory at the checkpoints. This feature of the blocking barrier obstacle allows construct various design and layout variants, each of which has certain advantages and disadvantages. The article section contains the study of the processes of the external loads influence on the hollow connecting elements of the blocking barrier obstacle on various volumes and ways of filling it with liquid. Mathematical models of the blocking barrier obstacle stability with liquid have been constructed in case of applying external loads. The analysis of theoretical studies results of the external loads influence on the hollow connecting elements of the blocking barrier obstacle has been carried out.
