摘要
通过对多台报废压力容器进行超压试验的声发射检测和对 5 0 0多台压力容器现场声发射检验数据的分析 ,给出了现场压力容器检验可能遇到的多种声发射源的特性。这些声发射源包括裂纹、夹渣、未熔合、未焊透等焊接缺陷的开裂和增长、残余应力释放、氧化皮的剥落、结构摩擦、泄漏、风吹、雨滴撞击和电子噪音等。笔者对这些声发射源的定位、分布和关联特性分别进行了分析与研究 ,并列举了大量的实例。
According to AE testing data of more than 500 pressure vessels, the characteristics of acoustic emission sources are listed and analyzed which could be encountered during field pressure vessel test. These AE sources include weld defect cracking, residual stress releasing, oxide scales peeling off, structural friction, leakage, electronic noise, and wind blasting et al. The characteristics of AE sources location, distribution and correlation of each acoustic emission source are shown respectively. A number of examples also are given.
