采用螢光磁性粒子探伤法代替磁粉探伤,检查車辆轉向架及均衡梁,不但使检查时間縮短了三分之二,而且使检查結果更为准确。 客車进厂大修时,輪对、轉向架构架及均衡梁經解体之后,将轉向架翻轉支于木架上,检查整个构架的疲劳裂紋及砂眼,发現80％以上的裂紋是由軸箱导框处向构架他处发展的。 The use of fluorescent magnetic particle detection instead of magnetic particle inspection, check the vehicle bogie and equalization beam, not only cut the inspection time by two thirds, but also to make the test results more accurate. Passenger car into the factory overhaul, the wheel, the bogie frame and the balance beam after disintegration, the bogie flip in the wooden frame, check the entire framework of the fatigue cracks and trachoma and found that more than 80% of the cracks by the shaft box guide Frame at the framework of other development.
