The use of the BIM model makes it possible to evaluate the key indicators of energy-efficient solutions: heat transfer coefficient, specific annual values of energy consumption, fuel consumption, and carbon dioxide emissions into the atmosphere.Purpose of research. Develop and determine the feasibility of introducing energy efficient solutions based on the use of a BIM model of a low-rise building.Methods. The methodology is based on the study of the introduction of modern building technologies and standards in the Penza region, as well as the analysis of positive solutions to similar situations in the Russian Federation. To achieve the goal, the following tasks were solved: a BIM model was developed and the energy efficiency of a typical residential building was assessed; options for improving the energy efficiency of a typical low-rise residential building were identified; an energy report was drawn up for standard and energy-efficient buildings and the expediency of introducing energy-efficient solutions into a standard project was substantiated.Results. When developing energy-efficient solutions, it is advisable to use modern digital technologies. The BIM model of a typical low-rise residential building makes it possible to identify thermal blocks, zones within each of them, as well as structural elements of the building through which the main heat losses occur and develop options for improving the energy efficiency of the building. Based on the thermal blocks and zones allocated in the building, energy-efficient solutions have been developed, thanks to which heat losses through window openings and the front door are reduced from 3.04 to 0.63 W/m2K and from 2.11-0.79 W/m2K, respectively. Heat losses due to changes in the design of enclosing structures: walls and floors above the first floor decreased from 0.28 to 0.25 W/m2K and from 0.18 to 0.15 W/m2K, respectively.Conclusions.The BIM model of a building makes it possible to effectively conduct a comparative analysis of standard and energy-efficient solutions for low-rise buildings, taking into account the features of the planning solution and regional climatic features.","PeriodicalId":443878,"journal":{"name":"Proceedings of the Southwest State University","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125605058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Development of theoretical premises for the new inertial viscometer, as well as the development of an approximate model of the viscosity fluid flow using convolutional neural networks and laser speckle contrast imaging data.Methods. The study consists of two parts. The first is devoted to a theoretical study of viscosity fluid flow in the toroidal channel of еру new inertial viscometer. The mathematical model of the flow includes the dimensionless equations of Navier-Stokes and convective heat conduction, the analysis of which made it possible to estimate the conditions for the uniformity of pressure and temperature fields. The numerical solution of the simplified Navier-Stokes equation was obtained by the control volume method. The computational experiment made it possible to identify additional operating conditions for the viscometer. The second part of the research is aimed at solving the problem of predicting the values of the shear strain rate on the tour surface and the flow rate. The approximate flow model is based on an ensemble of convolutional neural networks trained on data from laser speckle-contrast visualization of a fluid flow in a transparent tube.Results. The recommendations on the operating parameters of the inertial viscometer for the studied types of liquids in a given viscosity range are obtained. An approximate model has been developed in the form of an ensemble of deep neural networks, which makes it possible to determine the volumetric flow rate and the shear strain rate on the flow surface based on fluid flow images.Conclusion. The approximate Navier-Stokes equation obtained as a result of theoretical analysis for the flow of a viscous fluid in a toroidal channel can be used to numerical determination the kinematic viscosity. So, the necessary flow characteristics, such as volumetric flow rate and shear strain rate on the flow surface, can be found using the developed and pretrained convolutional neural network based on laser speck contrast imaging data. The test fluid can be any non-Newtonian fluid capable of reflecting coherent radiation. In particular, it can be physiological fluids, including blood.","PeriodicalId":443878,"journal":{"name":"Proceedings of the Southwest State University","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125243781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important task in the field of mechanical engineering is to increase production efficiency through the rational use of equipment, increase in labor productivity, and reduce the labor intensity of technological operations while ensuring the required quality. In manual production, only the working movements of the tool are mechanized. Installation, adjustment and replacement of the tool, as well as control over its condition, are carried out by the operator or the fitter. The solution to the problem of increasing the productivity of turning operations is possible only by automating auxiliary movements.One of several existing ways to reduce non-regrowth time is the automatic replacement of non-regrowth cutting inserts in turning tools. However, the known designs of such assembled cutters do not allow achieving the required quality of processing due to the ineffectiveness of damping vibrations arising during the cutting process. The machining accuracy during cutting largely depends on the design of the tool and the materials used in its manufacture. These materials in the construction of the tool dissipate vibration energy, thus reducing vibration and ensuring the required accuracy.The purpose and objectives of the development are to improve the quality of processing and tool life through design solutions that increase the rigidity of the cutters and significantly damping vibrations during turning. Methods. Use of high damping material to reduce vibration.Results. Increasing the efficiency of damping vibrations of the cutter due to vibration isolation of its prefabricated parts from the holder with a material with high damping.Conclusion.
