摘要
金属构件的硬度是其力学和机械性能的关键指标之一,因此硬度检测在工业生产中具有重要意义。传统的硬度检测方法通常采用压痕或划痕等方式,这种方法存在破坏性大、效率低等问题,难以满足现代化检测的需求,因此,无损检测方法成为当前研究的热点。随着声学、电磁学等领域的发展,基于这些技术的硬度无损检测技术应运而生。首先,对基于声学、电磁学的硬度无损检测技术进行系统的阐述,并探讨不同材料微观结构变化对检测特征的影响。通过对特征与微观结构之间的关系进行分析,深入地理解硬度无损检测技术的原理和应用。接下来,综述一些基于神经网络的新型信号处理方法,这些方法在提高检测精度和优化信号处理算法方面都表现出了巨大的潜力。最后,展望硬度无损检测技术的未来发展趋势。
The hardness of metallic components is a crucial indicator of their mechanical and physical properties,making hardness testing an important aspect of industrial production.Traditional methods of hardness testing,such as indentation or scratch tests,suffer from issues such as high destructiveness and low efficiency,rendering them unsuitable for modern testing needs.Therefore,non-destructive testing methods have emerged as a research hotspot.With the development of acoustic and electromagnetic technologies,non-destructive hardness testing techniques based on these technologies have been developed.Herein,a systematic description of non-destructive hardness testing techniques based on acoustic and electromagnetic methods is presented,and the influence of different material microstructural changes on the detection characteristics is explored.Through an analysis of the relationship between characteristics and microstructural changes,a deeper understanding of the principles and applications of non-destructive hardness testing techniques is gained.Subsequently,novel signal processing methods based on neural networks are reviewed,which have shown great potential in improving detection accuracy and optimizing signal processing algorithms.Finally,future development trends of non-destructive hardness testing techniques are discussed.
