中文摘要:
      为预防因液压导管相互之间,或与机体结构、设备机箱间靠磨引起的液压导管损伤或破裂,导致飞机液压系统故障或失效等问题,提出基于声发射技术的飞机液压导管靠磨损伤检测方法。通过检测导管靠磨损伤的声发射信号,在时域内进行特征参数分析,特征提取和损伤模式识别,从而判断导管是否存在靠磨损伤。在明确了导管靠磨的定义,介绍了导管靠磨的物理过程和机械损伤机理基础上,采用关联图分析对声发射信号特征参数进行分析和处理,并在飞机上进行了振动载荷作用下液压导管靠磨损伤检测实验,结果证明检测方法可行。
英文摘要:
      Aimed at the problems that damage or rupture of the hydraulic pipe caused by the friction between the hydraulic pipes, or between the hydraulic pipes and the body structure or equipment cabinet can lead to failure of the system, a method is proposed for detecting the frictional damage of the aircraft hydraulic pipe based on acoustic emission technology. A correct judgment of pipes whether there is abrasion damage of the catheter stems from in analyzing the characteristic parameter, feature extraction and damage pattern recognition in the range of time domain through detecting the acoustic emission signal of the abrasion damage of the catheter. In this paper, the definition of pipe grinding is defined, the physical process and mechanical damage mechanism of pipe grinding are introduced in detail, the characteristic parameters of acoustic emission signal are analyzed and processed by using correlation graph analysis, and the damage detection experiment of hydraulic pipe grinding under vibration load is carried out on the aircraft. The results show that the detection method is feasible.
