In such a case, the voltage impulse front duration lessens from 120 ns to 5 ns in a low resistance load (about 1 Ω). Numerical simulations have shown also that increase of the forming line length from 0.15 m to 0.45 m causes decrease of the impulse front duration from 10 ns to 3 ns and increase of the maximum output pulse voltage up to 1.8 times.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125622847","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}

It was established that with increasing salt content, the conductivity of the electrolyte initially increases, reaching a maximum at 1-1.3 mol/kg with a subsequent decrease, which is associated with ionic association. It is found that increasing the temperature and the introduction of the filler increases the number of free ions, which leads to an increase in conductivity. The introduction of nanoclay into the polymer electrolytes leads to an increase in their electrical conductivity. This method of modification is can be used for the development of polymer electrolytes with improved functional characteristics for lithium current sources.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125960003","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}

Modern vibration diagnostics systems are used for early prediction of malfunctions in electromechanical equipment. They are sometimes economically impractical. It is proposed to study the instantaneous electrical power of the engine to assess the mechanical vibrations of the electromechanical complex. A geared drive of a cooling tower fan is taken as an electromechanical complex, as mechanical vibrations arise there caused by the imbalance of the shaft. By means of mathematical modeling, studies of the impact of gear drive mechanical vibrations on the electric instantaneous power of an induction drive motor were carried out. The spectral analysis was carried out to identify the effect of vibrations.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128164494","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 developed design methodology takes into account design features of the mechanisms and describes the process of creating and transforming descriptive semantic models of electric drives. Different forms of such models on the one hand provide a visual representation of design factors, on the other allowing the use of a known mathematical apparatus to automate the search and analysis of design decisions. For electric drive requirements modeling SysML language is used. Further obtained model is converted into a semantic network in the form of a conceptual graph (CG). This graph has a mathematical description in the form of logical expressions and can be used by an inference machine for automatic analysis and synthesis of technical solutions. Other knowledge models of electric drives design are considered. To take into account the inconsistency of the requirements, the model in form of conceptual graph is transformed into description necessary for applying the GORE methodology tools. To take into account the incomplete certainty of design factors, a Bayesian network is built on the basis of the conceptual graph. The proposed set of semantic modeling tools is aimed at ensuring the completeness of the technical description of electric drives and automating the stage of their conceptual design.","PeriodicalId":365896,"journal":{"name":"2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751577","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}
