摘要
针对铁路货车提速、重载后车钩零件疲劳裂损日趋严重的情况,提出采用旋转磁场技术来解决车钩表面缺陷磁粉探伤的难点。
Regarding to the issue that fatigue and damage of coupler is becoming more and more critical with further speed increase of railway freight cars speed,magnetic partical testing technique is provided to test the surface defects of coupler by means of rotating magnetic field technology.
