Abstract: Bogie spring is one of the key components of the locomotive running gear. In the process of locomotive overhaul, using a spring fluorescent magnetic particle testing machine can effectively detect defects and cracks in the spring surface, so as to ensure the reliability of spring. This paper described the cautions of spring fluorescent magnetic particle testing machine, and summed up the spring breakage characteristics.
