(1)利用声发射技术检验多层包扎压力容器多层包扎式压力容器,由于其结构特点,一般常规无损检测方法无法对其进行全面检验。我们采用了声发射技术。经过对多层包扎容器声发射信号衰减规律的测定,声发射信号传播速度的测量、材质声发射特点的研究,声发射信号识别的研究,总结出声发射技术检验多层包扎压力容器的技术要点及检测方法,并对10多台多层包扎式氢气储罐进行了声发射检测。结果表
(1) Multilayer Wrap Pressure Vessels Using Acoustic Emission Technology to Test Multi-Wrapped Pressure Vessels Due to their structural characteristics, conventional general nondestructive testing methods can not be fully tested. We use acoustic emission technology. After the multi-layer dressing container acoustic emission signal attenuation law determination, acoustic emission signal propagation velocity measurement, material acoustic emission characteristics of the study, the study of acoustic emission signal recognition, summarizes the acoustic emission technology to test the multi-layer wrapped pressure vessel technical points And detection methods, and more than 10 multi-band bandaged hydrogen storage tank acoustic emission detection.
