Abstract (English):
Introduction. For 130 years of its history an automotive industry has become a major “locomotive” of global engineering, which is completely renewed every 10 years. The current stage of automotive technologies development is a competitive process that affects the principles of operation, design, and technology of all subsystems of high-volume cars. These significant engineering, technological, and manufacturing processes must be provided with adequate tools for testing of the totality of the responsible vehicle subsystems. Method. Nowadays the most informative method for non-destructive testing and measurements of complex engineering parts and components internal structure is an X-ray computed tomography (CT). Results. The article summarizes and illustrates the results of “Indintro” Company’s long experience in application of its high-energy X-ray CT systems for non-destructive testing of most critical automotive subsystems, and, above all, parts and assemblies of automotive internal combustion engines. Conclusion. The examples of obtained CT images and their analysis have convincingly shown that the high-energy CT testing of the internal structure of critical parts, components, and sensors of the state-of-the-art and perspective vehicles is an excellent tool for technology optimization, an instrument for finished products objective certification and increasing their reliability and competitiveness. The possibility of reliable quantitative comparison of technologies and design solutions of competing manufacturers, the ability to assess changes in the internal structure as a result of normalized mechanical or thermal influences allow additional useful information to be obtained, establish a cause-effect feedback between the technology and the characteristics of products internal structure. These advantages of CT non-destructive testing may become an important factor of new technologies development and reliability improvement of motor transport, which is experiencing a next phase of renovation.
