长管拖车气瓶声发射检测技术
The Technique of Acoustic Emission Inspection of Cylinders of Tube Trailer
摘 要
为发现长管拖车气瓶实际使用中存在的裂纹、腐蚀等危险缺陷, 保障长管拖车的安全运行, 根据长管拖车气瓶结构、尺寸和材料特点, 制定了相应的声发射检测方案。加工了裂纹和腐蚀减薄等人工缺陷, 对长管拖车气瓶进行了整体声发射检测试验。模拟了裂纹、线腐蚀、点腐蚀和面腐蚀等四种不同缺陷的监测过程和定位结果, 并对这些声发射源的定位、分布和关联特性分别进行了分析。

Abstract
In order to find the cracks, corrosion and other dangerous defects of in-service tube trailer gas cylinders, and to guarantee the safe operation of the tube trailer, corresponding acoustic emission testing program was worked out based on the tube trailer gas cylinders structure, size, material characteristics. Furthermore, corresponding cracks, corrosion thinning and other artificial defects were machined and the whole acoustic emission testing was perforwed to the tube trailer gas cylinders. This paper simulated the crack, line corrosion, pitting corrosion and surface corrosion defects in four different results of the monitoring process and positioning, and the characteristics of acoustic emission source location, distribution and associated features were analyzed.
