摘　　要：针对装备油液磨粒在线超声检测技术的重点和难点问题,该文在深入研究机械设备磨损机理和检测技术的基础上,分析了磨粒声散射理论模型的建立、超声散射信号处理、超声散射信号特征提取、磨粒智能识别及超声在线检测系统研发五个方面的研究现状,为后续的研究提供理论依据和技术支持。In order to solve the key problems of equipment wear debris on-line ultrasonic testing, we study in-depth on the mechanical wear mechanism and detection technology. Furthermore, we analyze the wear debris scattering model, the processing of ultrasonic scattering sig- nal, feature extraction of ultrasonic scattering signal, intelligent recognition of wear debris and development of online ultrasonic detection system, so that we can provide theoretical basis and technical support for the follow-up research.
