摘要

金属磁记忆检测技术是无损检测领域的一门新兴学科,简要介绍磁记忆的检测原理,应用自行设计的金属磁记忆检测系统研究45号钢在循环载荷下疲劳性能变化规律,试验表明把金属构件应力集中处的磁感应强度的切向分量的增加量作为阈值,可以预估剩余疲劳寿命。
        An effective method of monitoring the states of stress in equipment and structures is based on magnetic metal memory (MMM) ,which constitutes an essentially new line in fatigue damage diagnosis.Aiming at the problems of the magnetism memory technology applying in fatigue condition,this paper study the relation between the fatigue process and the magnetic memory signal and especially design a magnetic metal memory (MMM) test system.
