The development of such computer-aided design systems is associated with significant expenditure of time and labor resources and should be based on new approaches to the construction of mathematical and software, taking into account the specific features of the subject area and the nature of the tasks to be solved. In this paper, the problems associated with the modeling of maintenance of electrical complex are considered. A methodology for predicting components based on a single attribute within an experiment is demonstrated. The criterion in terms of risk assessment for the consumer is considered. The results of modeling the main parameters characterizing the quality of electrolytic capacitors are presented. After the tests are completed, the value of the predicted parameter is determined for each realization. The optimum value of leakage current, providing the minimum probability of error, for tantalum electrolytic capacitors with nominal capacity is shown. The results of the research can be useful for specialists working on electrical engineering complexes.","PeriodicalId":53093,"journal":{"name":"International Journal of Advanced Studies","volume":"188 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139367726","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 study was conducted using a stand for the diagnosis of shock absorbers developed by the Department of Road Transport of INRTU (Irkutsk National Research Technical University). Tests were carried out for five front suspension shock absorbers, one – a new serviceable shock absorber, the rest – shock absorbers that were previously in operation. The experimental dependences of the change in the resistance force of the shock absorber on the speed of movement of its rod are analyzed. The level of operational characteristics of the shock absorber under study was determined by comparing the obtained parameters with the parameters of the new shock absorber. The results of experimental studies are presented in the form of operational characteristics of tested shock absorbers and indicators that determine the level of operational characteristics of shock absorbers. The developed methods and the equipment implementing them make it possible to determine the functional dependencies and the level of performance of shock absorbers that were in the operating conditions of the vehicle.","PeriodicalId":53093,"journal":{"name":"International Journal of Advanced Studies","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139367808","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}

Tractors of traction class 8 must have high productivity and efficiency, in order to achieve the best results, in the shortest agrotechnical time. The need for the development of tractor designs of the 8th traction class is explained by current trends in the development of agriculture. The increase in the area of agricultural land sets manufacturers the task of increasing the speed of tillage, which entails an increase in the power and ergonomics of tractors. The necessary traction and layout characteristics of energy-saturated tractors of traction class 8 allow the implementation of articulated frames. The main task of the design is the development of a articulated frame with a cab rotation mechanism that will be able to fulfill the requirements for modern tractors of the 8th traction class. Purpose. Investigation of the forces of resistance to rotation of the articulated frame and the occurrence of a favorable moment for turning the cab using a model in the MATLAB Simulink environment. Methodology. Methods of mathematical modeling and analysis were used in the article. Results. The parameters showing the necessary forces for the rotation of the articulated frame and the occurrence of a favorable moment for turning the cab are obtained. Practical implications.

A mathematical model of a car quarter, a tire stretched string model, and a road surface microprofile generator were used in the study. The dependences of normal and lateral reactions along the distance traveled for three classes of roads were obtained with a change in the parameter characterizing the damping properties of the vehicle suspension. Mathematical statistics methods were used to analyze the dependences. It was found that the average value of the normal load changes little with a decrease in the damping properties of the suspension, while the standard deviation increases. The average value of the lateral force is reduced by 22%, with the standard deviation increasing by 1.6 times. The use of the Kolmogorov-Smirnov criterion for the analysis of implementations of lateral forces makes it possible to determine the permissible range of nominal values of the parameters of the technical condition of vehicle suspension shock absorbers. Purpose. Obtaining and analyzing patterns that describe the change in the lateral reaction of a car tire when it moves under the action of a lateral force and suspension vibrations, as well as when changing the damping properties of a shock absorber. Methodology. In the article were used the methods of mathematical modeling and also statistical methods of the analysis. Results. Dependences have been obtained that characterize the influence of the damping properties of the suspension on the magnitude of the lateral reaction when the wheel moves along a road with bumps and under the action of a lateral force. Practical implications. It is expedient to apply the received results by the organizations and institutions involved in the development of methods and means of diagnosing vehicles.","PeriodicalId":53093,"journal":{"name":"International Journal of Advanced Studies","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139366681","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}
