“…Static stationary rotation is characterized by low operating speeds (ω = 0) of the bridge machine, with the centrifugal forces being so small that they can be neglected. This reduces by one the number of unknowns and converts equations of motion (17) to equilibrium equations (the left parts are zero). The number of geometric coupling equations (10) is equal to the number of bridge machine propulsor supports, and the number of kinematic coupling equations ( 11) is reduced by one due to the exclusion of angular rotation speed ω:…”

The research is devoted to the topical problem of the efficiency of turning wide-span bridge machines in the track farming system. The research aims to study the curvilinear movement along the soil traces of a constant technological track of an arbitrary multi-supported bridge machine, considering its design and method of turning, parameters, modes of movement and loading. Experimental studies were conducted, involving the use of a modern strain track and specially designed equipment for electrical measurements of non-electrical quantities. The processing of research data was carried out on a personal computer. A methodology for compiling private models of turning off the bridge vehicle moving along the soil trace of the constant technological track was developed. As a result of the joint solution problem of the bridge machine turning, it is possible to determine all output parameters of curvilinear motion: trajectory, tractive forces, turning radius, slipping, and actual speeds. The force interaction of the bridge machine’s undercarriage with the soil trace of a constant track is presented based on flat sliding with a variable anisotropic friction coefficient of adhesion φyd, depending on the properties of the track. As the radius of the wheel, the width of its tire and the air pressure in it, as well as the vertical load that acts on it, the coefficient of traction of the bridge machine φyd increases, which may cause higher slippage. The adequacy of the model of stationary turning of the overhead machine is confirmed by experimental estimation of the resistance coefficient of the power onboard turning. The convergence of the theoretical and experimental values of this coefficient is within the confidence interval ± σ in the whole investigated weight range of the bridge machine prototype. This allows us to assess the influence of design parameters and schemes on the turning characteristics as early as the design stage of a new bridge machine, thus optimizing the design process. The results of the research can be applied to the organization of the process of turning the existing models of bridge machines

“…Of course, the issues involved are not new and there are some mathematical models that describe such phenomena. For example, such is the model of the agricultural tractor under the influence of an eccentrically applied load on the hook [20][21][22][23]. Most of the known mathematical models are based on the theory of lateral drift and focus mainly on the kinematics of motion [24][25][26].…”

One of the defining areas for further research in the world is the development of a set of technological measures for the introduction of resource-saving technologies and technical means, ensuring reduction in the need for material, technical and energy resources. The introduction of track and bridge systems in farming, the basis of which is a wide-span bridge traction vehicle, is really promising in this respect. The development of power-driven agricultural axle traction machines brings forward the necessity of setting and solving the problems of uncontrolled (passive) driving with its own tasks and solution methods. The aim of this research is to investigate uncontrolled passive steering of a bridge vehicle with power steering. The methodological basis of the theoretical research was the system approach, mathematical modelling, the laws of theoretical mechanics, the theory of tractors and vehicles, information technology and the use of PCs. A prototype of a wide span vehicle has been used as the object of experimental investigations. As a result of this research, it was found that the maximum value of asymmetrically applied shear pulling force of the wide span vehicle corresponds to the direction when its line of action passes through the centre of mass. For 1 kN of traction resistance of the bridge machine under study, the lateral slip when it moves along the compacted soil track of a constant tramline for each 1 m of the distance travelled was 0.011…0.015 m. In any deviation from this direction, there is an instantaneous rotational movement (shear) of the wide span vehicle where the total shear force is less than the maximum value. The anisotropy of this process results in a reversal of the hodograph towards a lower coefficient of traction of the wide span vehicle thrusters on the bearing surface of the permanent technological track. The adequacy of the meta-mathematical models of the passive steering of the bridge vehicle with the power method of control allows the solution of problems such as calculation of the minimum turning radius, evaluation of the technological track width, calculation of the maximum traction forces, selection of the rational control scheme under steady driving conditions, calculation and reduction of power on the turn, calculation of the maximum dynamic loads at the moment of active driving and others.

“…The influence of blockchain on cognitive management in the production process of industrial companies has been studied by scientists such as [3], [4]. Other researchers like [5], [6], [7] have explored innovative technologies to optimize the use of orbital hydraulic motors and planetary hydraulic machines while managing agricultural machinery and equipment supply chains in technological cycles to ensure product efficiency and competitiveness in the global market. However, these studies do not fully elucidate the functional relationship and financial architecture of financial and industrial companies' development, considering exogenous and endogenous factors influencing business model digitalization in the competitive corporate sector of the world economy.…”

The relevance of the article lies in examining the functional relationship between blockchain and fintech technologies in the innovative digital space of financial and industrial companies. The research aims to investigate the directions for the development of large integrated systems of financial and industrial capital, based on the principles of intensive production. The research methodology included the following methods: analytical (literature review, quantitative analysis), methods of comparison, generalization, and systematization. In particular, quantitative analysis was applied to calculate the index of digital cyber protection, which serves as an indicator and summarizes the safe properties of information resources in the digital space of banking institutions and their ability to prevent cyber-attacks on the financial and industrial capital of subjects in united spheres of economic activity. The results of the research have shown that the optimal criteria for the index of digital cyber protection are financially linked to industrial capital. The article substantiates the macroprudential policy of Ukraine’s banking sector based on blockchain regulators and fintech technologies from the EU, which foster the intensive development of technological competitiveness among financial institutions. The article can be useful for financial and industrial executives, banking institutions, consulting firms, and educators seeking insights into the integration of blockchain and fintech technologies.
