Determining the Stability of a Mobile Manipulator for the Transport and Assembly of Arches in the Yielding Arch Support

The yielding arch support is transported and installed in the face with the use of auxiliary machines. These activities in underground mining cause many problems, which have as yet not been solved. Currently, transport and assembly are carried out manually, using the roadheader and suspended rail, or various types of mounting platforms. The analysis of the structure of the existing solutions resulted in the development of an original structure that met the requirements of Polish mines. Developed jointly by FAMA Sp. z o.o. and the AGH University of Science and Technology in Krakow, Poland, the mining modular transport and assembly unit (MZT-M) will enable the transport and assembly of support arches in the mining face. Additionally, it can also be used to reload works, which is related to the work ergonomics in underground coal mining, which is the main energy resource in Poland. The most important problem to be solved in the case of this manipulator, due to the limited space in the excavation, is how to ensure its stability during various phases of its operation. Therefore, analyses were carried out to find a solution, which resulted in determining specific conditions and design requirements related to the operation of this manipulator.

Results of research of the combined seeder for strip sowing of grasses into sod

The development of ecological agriculture has aroused interest to the technology of increasing the productivity of natural forage lands, which consists in strip sowing of grasses with mechanical tillage in the sod of strips, the size of which ensures the successful development of seedlings without the use of chemicals. Several models of seeders SDK have been developed and mass-produced to implement this technology. A further development of this type of machines is the creation of a mounted seeder SDK-2.8M, intended for direct strip sowing of grass seeds into sod with the application of a starting dose of mineral fertilizers. To evaluate the efficiency of the seeder SDK-2.8M in the autumn of 2022, stand and field tests were carried out in the fields of the North-East Federal Research Center. Stand tests on sowing seeds of meadow fescue and red clover showed that the range of gear ratios of the seeder from 0.104 to 0.900 allows to set the seeding rate in the interval of 2.5-140.4 kg/ha. The sowing part ensures uniform distribution of seeds over the feed rolls and the stability of sowing by each feed roll in accordance with agrotechnical requirements. The deviation of the actual seeding rate from preassigned (6.0 kg/ha) for sowing fescue is 2.6%, clover – 2.3%; uneven seeding between feed rolls for fescue – 3.61%, for clover – 5.36%; seeding instability for fescue – 4.83%, for clover – 6.03%. Field tests revealed that the seeder stably performs tillage and clover sowing, maintains the working width and the installation depth of tillage. The average tillage depth was equal to 68 mm, the crumbling of the soil (fraction up to 25 mm) – 85.1%, the average depth of seeding – 16.4 mm, density after rolling – 1.1 g/cm3 .The use of a frame of the original design made it possible to reduce the number of assembly units of the tillage part and auxiliary mechanisms, which reduced the mass of the seeder by 640 kg, in comparison with SDKP-2.8M, while maintaining agrotechnical performance indicators.

CURRENT TRENDS IN THE DEVELOPMENT OF AUTOMATED COMPUTER MODELING SYSTEMS

This work is devoted to the study of the features of computer modeling systems, their analysis and development. The classification of modeling systems is given, the content and possibilities of existing systems are analyzed. Particular attention is paid to the division of all systems into groups according to the logic of construction and functionality. The advantages and disadvantages of the systems of each group are noted. Basic (light) level systems that work in vector space have a closed mathematical model. It is emphasized that the modeling process depends on the considerations of the designer and is reduced to the iterative process of creating a drawing. Features of systems are given and variants of 2-D and 3-D models of real technical units and mechanisms in AutoCAD and Compass-graph systems are given. The systems of the middle group, which are created for 3-D modeling of products and calculations, are considered. Working in such programs, the developer uses electronic copies of real models, which allows you to use the modeling logic of assembly objects. The most complex are the higher level systems used for complex products, which include elements of complex shape and dense layout of a large number of assembly units. The study identified software packages Unigraphics (NX), ProEngineer, Catia, Creo. Complex systems have an open mathematical model of construction and allow end-to-end analysis of the model according to certain parameters. The paper also draws attention to another approach to modeling. So-called PLM and BIM technologies greatly facilitate the process of modeling objects, using a system of well-organized computer models instead of a separate set of drawings. The rapid development of cloud CAD operating in a virtual computing environment is noted. From the made analysis the prospects of further qualitative development of automated systems by parallel development of equipment park together with modeling technology are resulted.

Assembly of π-Stacking Helical Peptides into a Porous and Multivariable Proteomimetic Framework.

The evolution of proteins from simpler, self-assembled peptides provides a powerful blueprint for the design of complex synthetic materials. Previously, peptide-metal frameworks using short sequences (≤3 residues) have shown great promise as proteomimetic materials that exhibit sophisticated capabilities. However, their development has been hindered due to few variable residues and restricted choice of side-chains that are compatible with metal ions. Herein, we developed a noncovalent strategy featuring π-stacking bipyridyl residues to assemble much longer peptides into crystalline frameworks that tolerate even previously incompatible acidic and basic functionalities and allow an unprecedented level of pore variations. Single-crystal X-ray structures are provided for all variants to guide and validate rational design. These materials exhibit hallmark proteomimetic behaviors such as guest-selective induced fit and assembly of multimetallic units. Significantly, we demonstrate facile optimization of the framework design to substantially increase affinity toward a complex organic molecule.

3D modeling of the aircraft air conditioning system

The study aim was to develop a 3D model representing the aircraft air conditioning system with the purpose of performing a numerical experiment in an automated environment of engineering analysis. The completeness of this model was associated with the required result of the numerical experiment. During the experiment, we simulated conditions for the flow of aerodynamic processes in the vicinity of the louvre integrated into the fuselage skin at the point of communication between the air conditioning system and the external environment. Of particular interest was that part of the air conditioning system, which directly affects the louvre strength. The Siemens NX computer-aided design system was used to form a digital copy of the original. The toolkit of this system allows high-precision geometric models to be designed. As a result, a 3D-model was obtained applicable to simulate external and internal aerodynamical processes in the digital environment of engineering calculations for evaluating the strength parameters of the studied part. This model is a combination of geometric objects formed by a set of assembly units. In particular, such elements of the air conditioning system as the cooling turbine, radiator, and valve, are considered. In order to recreate the complex geometry of the original assembly parts of these units, an algorithm for selecting and performing typical operations of the Siemens NX system was developed and optimized for constructing correct 3D models. The constructed 3D model of the aircraft air conditioning system can be used when simulating external and internal aerodynamical processes affecting the louvre strength in the digital environment of engineering calculations. The proposed model allows users to study the structure of aircraft air conditioning systems.

Crystal structure of progeria mutant S143F lamin A/C reveals increased hydrophobicity driving nuclear deformation

Lamins are intermediate filaments that form a 3-D meshwork in the periphery of the nuclear envelope. The recent crystal structure of a long fragment of human lamin A/C visualized the tetrameric assembly unit of the central rod domain as a polymerization intermediate. A genetic mutation of S143F caused a phenotype characterized by both progeria and muscular dystrophy. In this study, we determined the crystal structure of the lamin A/C fragment harboring the S143F mutation. The obtained structure revealed the X-shaped interaction between the tetrameric units in the crystals, potentiated by the hydrophobic interactions of the mutated Phe143 residues. Subsequent studies indicated that the X-shaped interaction between the filaments plays a crucial role in disrupting the normal lamin meshwork. Our findings suggest the assembly mechanism of the 3-D meshwork and further provide a molecular framework for understanding the aging process by nuclear deformation.

Counterintuitive Lanthanide Hydrolysis-Induced Assembly Mechanism.

The understanding of the hydrolysis mechanism of lanthanide ions is limited by their elusive coordination configuration and undeveloped technology. A potential solution by high-resolution mass spectroscopy studies is hindered by the lack of a stable model under electrospray ionization (ESI) conditions and the complexity of the spectra. Herein, it is demonstrated that diketonate ligands can efficiently stabilize the hydrolyzed intermediate cluster of Ln3+ under ESI conditions, and an effective mass difference fingerprint of isomorphism (MDFI) method is proposed, which can allow the determination of the nuclearity-number of the species without depth resolution. Thus, the hydrolysis of Ln3+ into an atomically precise hydroxide cluster is observed at the level of precise formulae. The species evolution upon hydrolysis is along the dominant path of {Eu3}-{Eu4}-{Eu9}-{Eu10}-{Eu11}-{Eu15}-{Eu16} and a nondominant path of {Eu3}-{Eu4}-{Eu8-1}-{Eu8-2} under the investigated conditions. The crystal of the {Eu16} species was obtained via low-temperature crystallization, and single-crystal X-ray diffraction studies show that its structure contains three octahedral {o-Ln6} units. The contradiction between multiple {o-Ln6} units in the structure and the absence in the formation process indicates that the repetitive subunit observed in the structure does not necessarily correspond to the construction units of high-nuclearity clusters. Photophysical measurements indicate that Eu16 cluster has a high total emission quantum efficacy of 12.8% in the solid state. This study provides fundamental insights into the formation, evolution, and assembly of small lanthanide hydroxide units upon hydrolysis, which is vital for the goal of directional synthesis of lanthanide hydroxide clusters.

Integrated fault-tolerant control of assembly and automated guided vehicle-based transportation layers

ABSTRACT The paper concerns the digital twin design and fault-tolerant control of a production system. The real laboratory system under consideration consists of two subsystems: an assembly part and an automated guided vehicle transportation one. The proposed approach focuses, simultaneously, on both concurrency and synchronization problems as they are inevitable in such a kind of modern systems. The research contribution deals with the development of an analytical description of both an assembly system and a multiple automated guided vehicles transportation layer along with algorithms that are able to determine an optimum sequence of starting individual operations. Subsequently, diagnostics and fault-tolerant control schemes are elaborated and applied to the two-layer system being investigated. The core advantage of the proposed approach is that it can compensate or eliminate the impact of some faults, e.g. delays occurring in the assembly unit or reduced velocities of transportation means. This makes it possible to keep the desired schedule as far as possible. The paper concludes with a series of illustrative use cases and comparisons which exhibit the performance of the novel approach in both cases, i.e. faulty and fault-free.

A label-free and enzyme-free fluorescent aptasensor for amplified detection of kanamycin in milk sample based on target-triggered catalytic hairpin assembly

Kanamycin residues in foods can cause serious adverse reactions in human body, and the accurate and sensitive detection of kanamycin is of great significance to ensure human health. In this work, we constructed a label-free and enzyme-free fluorescent aptasensor for quantifying kanamycin in milk based on target-triggered catalytic hairpin assembly. First, we designed an aptamer probe that contained an aptamer unit for recognizing kanamycin, a trigger unit for triggering catalytic hairpin assembly and a suppression unit for ensuring the stability of aptamer probe. In the initial state, the trigger unit was closed by suppression unit and inactive. After the aptamer unit recognized and bound to kanamycin, a free trigger unit was released to trigger the cycle hybridization reactions between hairpin probe 1 and hairpin probe 2, generating G-rich complexes and realizing enzyme-free amplification detection. Then, N-methylmesoporphyrin IX as signal molecules were combined with G-rich complexes to generate a significant fluorescent signal, which realized label-free detection. Thus, the aptasensor provided a well sensitivity for kanamycin with a detection limit of 0.26 ng/mL. And it possessed well selectivity and could distinguish kanamycin from its analogues, which stemmed from the specific recognition between kanamycin and aptamer. The aptasensor had great potential application value in the field of ensuring food safety.

Research into Carbon Dioxide Curing’s Effects on the Properties of Reactive Powder Concrete with Assembly Unit of Sulphoaluminate Cement and Ordinary Portland Cement

Excessive emissions of carbon dioxide can lead to greenhouse effect thus destroying the ecological balance. Therefore, effective measures need to be taken to reduce the emission of carbon dioxide. In this study, the influence of carbon dioxide curing on the mechanical strength and NaCl freeze-thaw deterioration of reactive powder concrete (RPC) with the assembly unit of sulphoaluminate cement and ordinary Portland cement was investigated. The ratio of sulphoaluminate cement ranged from 0% to 100% by the total mass of cement with the curing age ranging from 1 d to 28 d. The mechanical strength of RPC with 50% ordinary Portland cement and 50% sulphoaluminate cement containing the polypropylene fibers ranging from 1% to 4% by volume of RPC were investigated. Moreover, the following mass and mechanical strength loss rates, the carbonation depth, the chloride ion migration coefficient and the relative dynamic elastic modulus (RDEM) during NaCl freeze-thaw cycles were determined. Finally, the scanning electron microscope (SEM) and X-ray diffraction were applied in investigating the carbonation process of RPC. Results showed that the addition of sulphoaluminate cement could improve the mechanical strength of RPC at low curing age (lower than 7 d). However, when the cuing age reached 7 d, the sulphoaluminate cement demonstrated negative effect on the mechanical strength. Moreover, the carbon dioxide curing led to increases in the mechanical strength and when ordinary Portland cement was added the enhancing effect was more obvious. Furthermore, the carbon dioxide curing could effectively improve the resistance of NaCl freeze-thaw cycles and increase the carbonation depth. Finally, the increasing dosages of polypropylene fibers were advantageous to the mechanical strength and the resistance of NaCl freeze-thaw cycles. From the researching results of the microscopic performance, the carbon dioxide curing could improve the compactness of hydration products and reduce the content of calcium hydroxide especially at the curing age of 3 days.

Possible mechanisms underlying the dynamic assembly of calcium entry units: the role of temperature and pH

Skeletal muscle function is regulated by intracellular Ca2+ levels. Two main mechanisms control movements of Ca2+ ions from intracellular stores (i.e. the sarcoplasmic reticulum, SR) and from extracellular space: i) excitation-contraction (EC) coupling; and ii) store-operated Ca2+ entry (SOCE). SOCE allows recovery of extracellular Ca2+ during prolonged muscle activity, when the SR undergoes depletion. We recently discovered that prolonged exercise leads to formation of Calcium Entry Units (CEUs), intracellular junctions located at the I band that are formed by two distinct elements: SR-stacks and transverse tubules (TTs).

Antigen epitope-TLR7/8a conjugate as self-assembled carrier-free nanovaccine for personalized immunotherapy

Epitope-based vaccine is a promising personalized cancer immunotherapy; however, a simple and effective approach for its bulk manufacturing is challenging. Current vaccination strategies complicate the process by introducing unnecessary components such as additional delivery carriers, and assembly units. Herein, a type of toll-like receptor 7/8 agonist-epitope conjugate (termed as TLR7/8a-epitope) has been developed as a self-assembled and carrier-free nano vaccine platform, which effectively introduces the antigen and adjuvant with maximum precision, resulting in significantly enhanced dendritic cells (DCs) activation through the MyD88-dependent TLR signaling pathway. TLR7/8a-epitope nanovaccine can prolong the local retention and increase drainage efficiency into the lymph node, eliciting a significantly higher level of CD8 T-cell immunity than those of conventional vaccine formulations. The immunization with TLR7/8a-epitope nanovaccine in mice can not only resist the invasion of B16 cancer cells, but also produce significant therapeutic effects against established B16 melanoma tumors. Therefore, the TLR7/8a-epitope nanovaccine, developed by the direct chemical conjugation of antigen peptide with immunoadjuvant, has great advantages of clear and leanest compositions, controllable and definite preparation process, and remarkable therapeutic effects, representing a new appraoch for personalized cancer immunotherapy. Statement of significanceHerein, a kind of toll-like receptor 7/8 agonist-epitope conjugate was developed and spontaneously self-assemble into nanostructure in aqueous solution without the use of any additional constituents, which can be termed as unique carrier-free nanovaccine platform, providing effectually the leanest vaccine components with maximally and precisely loading of antigen and adjuvant.Significantly, the nanovaccine augmented the immunogenicity of antigenic peptide by increasing DCs activation through MyD88-mediated TLR signaling pathways and promoting T-cell priming. Moreover, nanovaccines could prolong the local retention and further increase the efficiency of drainage into dLNs, which was contributing to efficient initiation of epitope-specific memory and effector T-cell immune responses, leading to effective prophylactic and therapeutic antitumor effects.

Be subjected to conversion various functionally uniform elements of the corresponding parts or assembly units, provided with technological parameters of design quality, are sequentially redistribute in the structure of the initial blanks along the route of operations. For the synthesis of the structure of the initial blanks, the methods of system technology are used, and for the decomposition — the methods of cutting. Three technological schemes are included in the structure of systems of working machines as elements: for basing initial blanks and blanks in working machines; for basing the shape elements be subjected to conversion into working machines and their geometric formation on working machines; for basing parts and assembly units into construction products.

Choice of means and methods for measuring geometric dimensions in the manufacture of special equipment

Measuring equipment is an integral part of any production. The quality, and, accordingly, the competitiveness of products is largely determined by the state of the measuring procedure in production. The manufacture of special equipment requires high-precision production of parts of complex geometric shapes. Since the material from which the parts are made is usually expensive, the production must be highly efficient, and the control of the resulting product must be highly accurate. Most parts of special equipment have a complex profile, and the manufacture of such parts is a rather laborious process, the result of which is controlled without fail. Quality control of the resulting complex-profile parts takes a lot of time and measuring tools. The execution of measurements accounts for up to 15% of labor costs. The article is devoted to solving the problem of choosing means and methods for controlling the geometric dimensions of parts and assembly units, depending on the conditions of design documentation, technological process and design. Geometric dimensions are length and thickness, diameters (external and internal), parallelism of sides, angles, threaded holes, roughness, etc. The control of these parameters is the most specific and responsible in production shops, central measuring laboratories, technical control departments. In industrialized countries, these types of measurements account for 85% – 90% of all existing types of control, while the assessment of the accuracy of shape and size depends on the degree of measurement accuracy. The article considers the development of the scientific foundations of the actual scientific and technical problem of increasing the efficiency of geometric measurements, the choice of control methods, the justification for the need to use one or another measuring instrument. Methods and methods for controlling geometric dimensions and angles by various technical means and devices are presented, taking into account the technological process of manufacturing parts and assemblies.

СОВЕРШЕНСТВОВАНИЕ МЕТОДИКИ ПРОГНОЗИРОВАНИЯ РАСПРЕДЕЛЕНИЯ РЕСУРСА МАШИН И ИХ ЭЛЕМЕНТОВ

The structural and technological modernization of machines as a whole, as an integral part of maintenance in its modern sense, acquires a more rigorous scientific basis and ultimately contributes to a significant improvement in the quality indicators of machines. It is this approach to solving the problems of increasing the life of machines, based on a deep analysis of the results of scientific research, operation and repair experience, that will allow us to achieve positive results. During repair, it is impossible to automatically achieve the same high degree of accuracy of assembly of aggregates and machines as in the process of mass production of new samples, and, consequently, in these cases, manufacturing errors of assembly can have a more noticeable effect on reducing the life of aggregates and machines. An objective assessment of such an impact, of course, is possible only on the basis of the results of special studies to establish the dependence of the service life of parts on certain technological factors. Variants of structural reliability schemes have been compiled depending on the ranks of repair costs, based on the assessment of the probability of the appearance of the limiting condition of machines by the levels of maintainability of its assembly units. The probabilistic relationship obtained in this way will be maintained throughout the entire period of operation of the machine until its overhaul, provided that during this period the level of maintainability of its components remains unchanged. On the basis of structural schemes and analysis of the background of production and operation, the requirements for the resource indicators of assembly units are determined. The analysis of the expected operating conditions and loading modes of the machine, as well as taking into account the technological factors of its manufacture (repair), allows you to establish the resource distributions of the machine of the first major repair and the numerical value of the coefficient of variation of this distribution. An expression was obtained for restoring the probability distribution of providing a machine resource, calculations using which showed that the distribution function restored according to the structural scheme has parameters corresponding to the pre-selected distribution of the machine resource.

Разработка методического и математического обеспечения реализации стратегии выявления критичных требований к сборке высокоточных изделий

The problem of improving the production of highly-precise devices and machines has primary importance. It is caused by the fact that the quality and accuracy of production of such devices impose increasingly stringent requirements, while standard approaches intended to ensure these criteria are insufficiently multipurpose. The developed approach – a complex of formalized design procedures for systems for accounting the requirements for the assembly of highly-precise goods when designing technological processes of mechanical treatment – allows solving these problems. However, it is necessary to develop additional solutions to ensure the relationship between the design and technological preproduction. The relevance of the study is in the solution of an important problem – the improvement of the procedure for carrying out the design-dimensional analysis within the system for accounting the requirements for the assembly of highly-precise products when designing technological processes of mechanical treatment. To solve this issue, the authors proposed the technique of component separation of a highly-precise good based on the identification of a base component / assembly unit and specified a mathematical model for the formation of a conjugation graph and a dimension graph, which is necessary to identify critical (vital) requirements to assembly and carrying out the design-dimensional analysis. Introducing the proposed techniques will allow choosing rational technologies for producing parts at further stages of implementation of design procedures of the system for accounting the requirements for the assembly of highly-precise goods when designing technological processes of mechanical treatment. In turn, it will cause labor intensity reduction and cutting the time of production of highly-precise goods and will allow decreasing costs during design-technological preparation within the conditions of multiproduct manufacture.
