摘要
剩余寿命预测是再制造工程的核心内容之一,金属磁记忆技术在再制造毛坯寿命预测领域极具潜力。文中概述了金属磁记忆信号的特征、微观物理检测机制的研究结果,探讨了利用金属磁记忆技术表征疲劳裂纹萌生及扩展寿命的途径和方法,并介绍了该技术在再制造毛坯寿命评估领域的初步应用。
The residual life prediction is one of the cores of the remanufacturing engineering. Metal magnetic memory testing （MMMT） is a highly promising tool in this field. This paper gives a presentation of results of basis theory researches on the essence of MMMT signals, the micro-physical testing mechanism. The prediction approach of fatigue crack initiation life and fatigue crack propagation life is determined by means of MMMT. The application of MMMT in remanufacturing blank life prediction is also introduced at the end of the paper.
