摘　　要：声发射检测系统是一种实时监测结构变化的无损检测设备,广泛应用于飞机结构强度试验,且粘贴于试验件表面。本文针对其不易拆卸的声发射传感器的计量校准需求,研究设计了一套适应的试验现场原位计量校准方法,确保该类传感器量值溯源的一致性,满足质量与适航要求。Acoustic emission testing system is a kind of nondestructive testing equipment used for real-time monitoring of structural changes, which is widely used in aircraft structural strength test and pasted on the surface of test parts.In view of the measurement and calibration requirements of acoustic emission sensors that are not easy to disassemble, a set of suitable in-situ measurement and calibration methods are designed to ensure the consistency of the measurement traceability of such sensors and meet the quality and airworthiness requirements.
