铁路客车轴承外圈磁粉检测的非相关磁痕分析及改进措施
Analysis and Measures of Noncorrelated Magnetic Trace on Magnetic Particle Testing of Bearing Outer Ring of Railway Passenger Car
-
摘要: 铁路客车轴承外圈制造过程中的磁粉检测时，会产生批量性的非相关磁痕，经过分析得知，这些磁痕是由材料本身的金属组织和带状组织的不均匀引起的，并提出了改进措施，以供同行参考。Abstract: Magnetic particle inspection of railway bearing outer ring in the manufacturing process, produces a batch of noncorrelated magnetic trace, the reason is the banded structure and organization nonuniform of the metal itself, and puts forward some improvement measures, for reference.
