摘要
简述及比较了主要的残余应力无损测量技术,重点为磁力法。并介绍一台新的磁力仪MAPS,且对MAPS及传统磁力仪作了比较。同时以X射线及中子衍射得到的结果验证了MAPS的可靠性。也介绍了文献上较少见的火车钢轨残余应力分布图。
This paper introduces and compares the most widely used techniques in the non-destructive evaluation of residual stress. The emphasis is on magnetic methods. This paper also introduces a new residual stress measuring kit, MAPS, which is compared with other conventional devices. Since researchers in the mainland are also making a similar device, this paper will be of value to them. This paper also compares the results obtained from MAPS, neutron diffraction, and X-ray.
