The results of the competitive selection to support scientific and scientific-technical projects have been summed up. They are jointly carried out by educational and scientific organizations located in the territories of St. Petersburg and the Republic of Belarus.
Among the winners is the scientific and technical project “Development of technology for producing composite materials based on ceramics and products using the additive manufacturing method.” SPbPU is represented in it by the scientific team of the Institute of Mechanical Engineering, Materials and Transport under the leadership of the director of the institute, Professor Anatoly Popovich. Belarusian side – Institute of Powder Metallurgy named after Academician O.V. Roman under the leadership of the director, academician of the National Academy of Sciences of Belarus Alexander Ilyushchenko.
q>It was pleasant news for us to learn that our application was supported in a competition of joint scientific and technical projects, where St. Petersburg Polytechnic University acts as a performer of work directly related to the development of 3D printing technology. And our Belarusian colleagues from the Institute of Powder Metallurgy, having extensive experience in working with powder ceramic materials, will take an active part in the development of raw materials suitable for the 3D printing process. It is worth noting that the results obtained within the project will find their application in the manufacture of parts for equipment in the oil production and oil refining industries, as well as in the manufacture of components for the radio-electronic industry,” noted project manager Anatoly Popovich.
During the project, scientific teams will develop technological solutions to implement the process of forming complex-profile parts from polymer composite and ceramic materials using additive manufacturing technologies. In addition, the knowledge gained will be actively used in the transformation of master’s and postgraduate programs at the Polytechnic University and the Institute of Powder Metallurgy. This will make it possible to attract talented students and researchers into real R&D.
The responsible executor of the project, Anton Sotov, shared the details of the project: At the first stage, our project is aimed at manufacturing parts from polymer-ceramic material using FDM technology. Further, at the second stage, it is planned to manufacture parts from ceramic material, where, in addition to developing the technology for printing pre-ceramic filament, the process of burning out the polymer binder will also be developed, followed by high-temperature sintering of the material. Oxide and non-oxide systems, including piezoceramic materials, can act as ceramic fillers.
According to the results of the competition, held jointly by the Russian Science Foundation and the Belarusian Republican Foundation for Basic Research, the winners included a joint project of St. Petersburg Polytechnic University – ITMO NAS of Belarus entitled “An integrated approach to creating a scientific basis for the design of energy-efficient heat exchangers with air-cooled finned tube bundles operating under dominant conditions.” effects of free convection.”
Teachers and researchers of the Higher School of Applied Mathematics and Computational Physics and the Research Laboratory of Hydroaerodynamics of the Institute of Physics and Mechanics of St. Petersburg Polytechnic University in collaboration with researchers from the Turbulence Laboratory of the Institute of Heat and Mass Transfer named after A.V. Lykov NAS of Belarus began research aimed at creating a methodology for thermal-hydraulic calculation and design of working units of air-cooling devices and heat exchangers (ACO and HCO).
The international scientific team includes 11 researchers from Russia and Belarus. The scientific group of St. Petersburg Polytechnic University was headed by associate professor of the Higher School of Applied Mathematics and Higher Faculty Marina Zasimova, and the group of ITMO NAS of Belarus was headed by researcher Galina Marshalova. The goal of the three-year project is the development of a scientifically based methodology for thermal-hydraulic calculation and design of working units of air coolers and air coolers: bundles of pipes with external fins, cooled externally by air flow in modes that arose under the influence of the effects of free convection and natural draft.
The scientific novelty of the project, in addition to the unconditional value of the expected experimental and computational data and their physical interpretation, will consist in the fact that it can become an important step towards the introduction of modern information technologies into the practice of designing elements of extremely widespread energy and technological equipment, emphasized Marina Zasimova.
Project of the Advanced Engineering School of the St. Petersburg Polytechnic University “Digital Engineering” (PISH SPbPU) “Development based on digital twin technologies and artificial intelligence, as well as the use of a digital model of a technical system with elements from the new structural material MONICA, operating under conditions of sliding friction and mechanical Fatigue” won the competitive selection to support joint scientific and scientific-technical projects.
The research on the project is carried out by a scientific group, which includes from Russia: the scientific director of the project, the head of the Advanced Engineering School of SPbPU “Digital Engineering”, the world-class Scientific Center of SPbPU “Advanced Digital Technologies”, the Competence Center of the National Technological Initiative of SPbPU “New Manufacturing Technologies” , Engineering Center “Computer Engineering Center” (CompMechLab®) SPbPU Alexey Borovkov; Nikolay Vatin, head of the Scientific and Technological Complex “Digital Engineering in Civil Engineering”, PISH SPbPU; Researcher of the automobile and equipment development department of the Engineering Center “Computer Engineering Center” (CompMechLab®) NIS SPbPU Ivan Martynov and responsible project executor, leading engineer of the automobile and equipment development department of the Engineering Center “Computer Engineering Center” (CompMechLab®) NIS SPbPU Igor Shander.
The scientific group from the Belarusian side is represented by employees of the United Institute of Mechanical Engineering of the National Academy of Sciences of Belarus. The project manager is Academician-Secretary of the Department of Physical and Technical Sciences of the National Academy of Sciences of Belarus Sergei Shcherbakov, he is assisted by Doctor of Physical and Mathematical Sciences Vadim Kukareko.
Alexey Borovkov spoke about the uniqueness of the project and its significance for each party: A unique feature of the proposed project is the combination of numerical modeling of the stress-strain state of model samples and artificial intelligence, in particular neural networks, which will make it possible to quickly determine extreme stress values without conducting numerous lengthy finite element tests calculations. This project will combine the experience of Belarusian and Russian partners in the numerical analysis of material fatigue.
During the project, it is planned to develop software for numerical calculations of the stress-strain state of power systems and the dependencies of maximum stresses in the system for various ratios of contact and non-contact loads. This result is of a private nature. However, the components of the software product being developed can be used to create software for further research, both by the Belarusian and Russian sides,” commented Igor Shander, the responsible executive of the project.
To solve research problems, project participants will develop mechanical and mathematical models of the shaft/liner power system used in testing for mechanical, frictional and friction-mechanical fatigue. They will conduct computer modeling and analysis of the spatial stress-strain state of the power system, in which the liner is made of the new structural material MONICA, and will also create a neural network that models extreme stress values in the shaft/liner system depending on the magnitude of contact and non-contact loads.
Our joint project with SPbPU is multifaceted. As a result of its implementation, we will gain new knowledge about the complex interaction of two most important phenomena that damage modern critical equipment: sliding friction and mechanical fatigue. In addition, we will evaluate the possibility of using the new structural material MONICA to effectively resist these phenomena. The most important thing is that, based on finite element modeling and approximation of its results with an artificial neural network, we will create a digital model of a technical system operating under conditions of frictional-mechanical fatigue. This model will allow not only to correctly and quickly assess the state of the system without labor-intensive long-term calculations, but also to control its damageability to ensure the required durability,” noted Sergey Shcherbakov.
