一、引言声发射监测是一种动态无损检测方法。压力容器静压试验时的声发射监测,目的在于发现压力容器存在的潜在危险缺陷,定出缺陷位置和有害程度,以保证压力容器的安全运行。我们对φ2m带接管缺口模拟球形容器静压试验吋进行了声发射监测,希望能通过试验,验证AE监测的有效性和可靠程度,并对静压试验时本底噪音,传播衰减、定位精度、评价有害度的方法等技术问题作一探讨。并希望通过模拟容器试验能取得一些检测经验,发现问题,积累数据,为实际产品测试奠定基础。 First, the introduction of acoustic emission monitoring is a dynamic non-destructive testing methods. The acoustic emission monitoring during the static pressure test of pressure vessel aims to find the potential dangerous defects existing in the pressure vessel and determine the location and harmfulness of the defect so as to ensure the safe operation of the pressure vessel. We conducted the acoustic emission monitoring of φ2m static pressure test with a notched analogue spherical vessel, and we hope that the validity and reliability of AE monitoring can be verified through experiments. The noise floor, propagation attenuation, positioning accuracy, Evaluation of the degree of harmfulness and other technical issues to explore. And hope that through the simulation of container testing can get some testing experience, identify problems, accumulate data, and lay the foundation for the actual product testing.
