工业CT无损检测技术在内燃机产业中的应用

Application of Industrial CT Nondestructive Testing Technology in Internal Combustion Engine Industry

摘要: 内燃机产业是我国制造业的重要组成部分，在支撑国民经济发展、推动装备升级与践行“双碳”战略中发挥不可替代的作用。随着内燃机制造技术的飞速发展，内燃机零部件对于无损检测需求日益增多，传统无损检测方法(如超声、射线)难以实现复杂结构件的精确、定量和三维分析。本文首先简述了工业CT的检测原理和检测特点，随后介绍了工业CT在内燃机产品开发、设计验证、生产制造、质量控制和售后服务等环节中的应用，工业CT凭借其适应材料广、检测精度高等优势能够很好地解决目前内燃机产业中的检测难题。

Abstract: The internal combustion engine industry is an important part of China’s manufacturing sector and plays an irreplaceable role in supporting national economic development, promoting equipment upgrades, and implementing the “dual carbon” strategy. With the rapid advancement of internal combustion engine manufacturing technology, there is an increasing demand for non-destructive testing of engine components, and traditional non-destructive testing methods (such as ultrasound and radiography) struggle to achieve precise, quantitative, and three-dimensional analysis of complex structural parts. This paper first briefly describes the detection principles and characteristics of industrial CT, and then introduces the application of industrial CT in various stages of internal combustion engine products, including product development, design verification, production and manufacturing, quality control, and after-sales service. With its advantages of being suitable for a wide range of materials and offering high detection accuracy, industrial CT can effectively address the current testing challenges in the internal combustion engine industry.
