Abstract
With the rapid development of modern industrial technology, the performance and reliability requirements of mechanical parts are increasing day by day, and the accurate detection of the internal defects of the parts has become the key link to ensure the safe operation of mechanical equipment. Infrared technology, as a non-contact and non-destructive detection means, has shown great potential in the internal detection of mechanical parts. This paper aims to explore the application of infrared technology in the internal detection of mechanical parts and its optimization countermeasures. Firstly, the basic concepts and characteristics of infrared radiation and the development of infrared technology provide the theoretical basis for the application of infrared detection technology in the internal detection of mechanical parts. Subsequently, the advantages of infrared technology in the detection of mechanical parts are analyzed in detail, including the application of infrared thermal imaging technology in defect detection, the role of infrared spectroscopy analysis in the detection of material composition, and the practical cases of infrared detection technology in fault diagnosis. Then, the paper deeply analyzes the shortcomings of infrared technology in the internal detection of mechanical parts, such as the limitation of detection accuracy and resolution, the interference of environmental factors, the detection problems of complex structure parts and the complexity of data processing. Finally, according to the above deficiencies, the corresponding optimization countermeasures are proposed, including the technology of improving the detection accuracy and resolution, the strategies to reduce environmental interference, the innovation of the detection technology of complex structure parts and the optimization of data processing and analysis methods. This study not only provides theoretical support and practical guidance for the application of infrared technology in the internal detection of mechanical parts, but also provides a reference for the development direction in the future.
