Вибір діагностичних методів та аналіз чинників впливу на довговічність деталей транспортних засобів для забезпечення максимального залишкового ресурсу

Abstract

Under modern conditions of the automotive industry development, one of the key tasks is to ensure the durability and reliability of vehicle parts. To achieve this goal, it is important to choose the right diagnostic methods, allowing timely detection of defects, predicting the residual resource and preventing premature failures. The use of a systematic approach to technical diagnostics contributes to increasing the efficiency of technical maintenance, optimizing repair processes and ensuring the safety of vehicle operation. Particular attention is paid to the analysis of factors that affect the durability and reliability of parts. Among them are the quality of materials, design features, manufacturing technology, operating modes and load conditions. Considering these aspects as a whole enables to more accurately determine the residual resource and form a maintenance strategy in accordance with the real technical state of components and assemblies, and not only according to regulatory deadlines. The article analyzes in detail modern diagnostic methods, including visual inspection, non-destructive methods (ultrasonic, magnetic, capillary, X-ray), as well as automated monitoring systems. Their advantages, disadvantages and possibilities of integration into the practice of car service enterprises are considered. Special emphasis is placed on the combination of the conventional and progressive technologies, which allows achieving maximum accuracy of diagnostic results and increasing the efficiency of repair processes. Based on the analysis, recommendations are proposed for optimizing the choice of diagnostic methods depending on the type of parts and their operating conditions. The results of the study can be used both in the educational process of training specialists in technical operation and repair of cars, and in the activities of car service enterprises. The practical implementation of the proposed approaches will ensure the extension of the residual resource of parts, reduction of repair costs and increase of the overall level of reliability and safety of vehicles.
