Abstract:

Links of variable length are used in various robotic products: robotic manipulators with telescopic links, anthropomorphic robots, exoskeletons with links of variable length, in which the distance between the axes of rotation in the hinges changes, similar to the human musculoskeletal system. The variable - length link model consists of two absolutely rigid inertial sections located at the ends of the link and a weightless variable - length section located in the middle of the link. At one end, the link is connected to a fixed support by means of a combination of two cylindrical hinges. To control the movement of the link, two electric motors are installed in the hinges, transmitting the torque by means of gearboxes to the link. The third motor controls the change in the link length. A system of Lagrange - Maxwell differential equations of motion has been compiled. Selected, three electric motors. Modeling of the link movement was carried out and positioning errors were estimated.

Abstract:

One of the problems of conducting certification tests of body armor samples, which appeared due to the ambiguity of the requirements of the new domestic national standard GOST 34286-2017 for the indicator of the resistance of the protective structure of the body armor to the effects of a regulated means of destruction, is considered. This indicator can be evaluated by several accredited organizations using each of them quite different parameters in terms of physical meaning and the criterion of admissibility. The analysis of the relevant methods currently used in Russia, the indicators used in them and the methods of their assessment is carried out. Suggestions are given on the possibility of their further use. The necessity of searching for optimal methods for determining the technical parameters of the armor impact, which can be used to assess the protective effectiveness of samples of bulletproof vests of various compositions, is shown.

Abstract:

The article is devoted to solving the actual issue of obtaining photo plans and maps without using a planned - altitude basis. It is proposed to improve the method for determining the elements of external orientation by jointly processing a pair of overlapping frame images of the terrain. A special feature of the approach is the possibility of its full automation based on the comparison of central points on overlapping images. As a result, it is possible to obtain photoplanes and orthophotoplanes in a time mode close to real time on board the aircraft. The proposed method for obtaining elements of external orientation of images will improve the accuracy of determining the coordinates of terrain objects during remote sensing without the use of planned altitude training.

Abstract:

A method of automated control and management of technical protection of information from leakage through the channels of compromising emanations is proposed. The method allows providing the necessary level of information security on localized and distributed objects of informatization in real time. The idea of the method is based on monitoring the occurrence of possible channels of information leakage through spurious electromagnetic emanations and the use of backup means of technical protection of information in the event of their manifestation. A variant of the implementation of the method in the form of an automated system is given.

Abstract:

The technique described in the article was developed on the basis of quantitatively substantiated relationships between particular parameters obtained when modeling a special - purpose communication node of an arbitrary structure and the elements that make up it. The algorithm consists in recursive recalculation using the developed models of indicators of the investigated property of all elements that make up the communication node, for various options for their presentation. The selection and justification of the initial data, indicators and criteria was carried out, the main restrictions and assumptions were adopted, the correct formulation of the problem was carried out. Bringing the developed algorithm to software implementation made it possible to significantly reduce the time for carrying out calculations, the analysis of the results of which made it possible to reasonably formulate the main directions for increasing the indicators of this property.

Abstract:

The extensive powers of privileged users in mission - critical automated systems (AS) enable them to neutralize some control and information protection functions. However, attacks by privileged users remain undetected for a long time. So, deliberate or accidental actions of privileged users can cause disruption or termination of critical AC. The article considers peculiarities of privileged user activity control architecture implementation. It presents a practical approach to controlling the actions of privileged users in a critical system, based on an integrated use of various information security mechanisms.

Abstract:

The article considers the weapons used in the organization of underwater sabotage defense, its design, technical characteristics and used ammunition. An analysis of the characteristics of hand grenades used in preventive grenade throwing in the waters of ports was carried out, which showed that their use is effective provided that they are blown at different depths, but the device of the fuses used does not allow adjusting the depth of their blasting. The invention proposes a design solution of a remote detonation fuse for hand grenades due to making changes in the system of initiating and protecting the remote fuse V-90 to artillery shells, by introducing a fuse with wax - flame and initiating elements into its composition, which will increase the effectiveness of preventive grenade launchers.

Abstract:

The article investigates the question of the influence of the availability of a shipborne artillery installation on the efficiency of solving a typical combat mission. Availability is expressed as an integral indicator of reliability, that is, the reliability of a shipborne artillery installation, taking into account the possibility of prompt elimination of a failure due to the capabilities of integrated logistic support. The probability of successful completion of a typical combat mission is presented as an efficiency criterion. On the basis of the information - system risk management methodology, the effectiveness of the firing of an artillery mount is analyzed in the presence of integrated logistic support, taking into account the possibility of failures. An analysis of the reliability of a shipborne artillery installation by the method of topological similarity is presented. The results obtained can be used in the design of advanced artillery installations of a given reliability and efficiency.

Abstract:

The article discusses methods for impregnation ballistic fabric due to the additional processing of fabric threads with various compositions, including the high molecular weight organic compound and chemical reaction catalyst. The treatment of ballistic fabrics with chemical solutions was aimed at increasing the frictional interaction of the threads of the fabrics due to the appearance of additional bonds between the elementary threads, as well as between the warp and weft threads. Additional connections make it possible to redistribute the energy of the striking element (bullet, fragment) to the entire volume of the material and thereby increase the protective properties of the material without weighing down the armor. The article describes the essence of the experiment, shows the procedure for its implementation, including testing tissue samples and processing numerical results. Concentrations of chemical compounds were selected experimentally, which give the maximum increase in the breaking load of ballistic tissues.

Abstract:

In satellite radio links, the nonlinearity of the power amplifier causes amplitude - phase distortions, which lead to errors in signal reception. The article presents a software package that allows one to study the effect of distortions of the amplitude and phase of a signal in a repeater power amplifier on the ability of the phase synchronization subsystem to reduce the likelihood of bit errors. The Saleh nonlinear model is used as a nonlinearity model in the software package. For various signal - code structures of the DVB - S2 satellite communication standard, the results of reducing the noise immunity are determined.
