摘　　要：单种电磁无损检测方法检测对象较为单一,而且缺陷的定量评估精度和检测的可靠性不高,采用集成化无损检测技术是解决这些问题的有效途径。该文在前期研究基础上,利用脉冲激励频谱成分丰富的优势,将脉冲激励方式引入电磁无损检测领域,深入研究脉冲激励下多种电磁无损检測方法的集成化问题,通过突破多种电磁无损检测方法的原理集成、一体化传感器设计等关鍵技术,从而在解决传统正弦激励的电磁无损检测技术不足的基础上,进一步拓展和提高集成化电磁无损检测技术的研究领域和理论水平。预期研究成果将进一步推进集成化无损检测技术的发展进程,对于提高大型装备无损检测的效率及缺陷定量评估的精度都具有十分重要的理论意义和实用价值。The single electromagnetic method can be used to detect only one kind of material, the precision of defect quantification and dependability of defect detection are not high. The integration of multiple methods is an effective solution to this problem. On the basis of the previous research work, the pulsed excitation can provide wideband exciting frequency components and this excitation mode is introduced into the field of electromagnetic NDT technique.The key problems of the integration of multiple electromagnetic methods and integrative probe are studied in this paper, and the disadvantages of the single frequency excitation technique are overcomed. This researching achievement expected will extend and improve the research domain and level of Integration NDT technique, and also has an important theoretical meaning and a practical value for improving defect detecting ability of nondestructive testing.
