Abstract

High-speed railway in the world is developing towards the direction of high-speed and heavy load. The safety of train is an important part of the research of high-speed train. The online detection based metal magnetic memory method is proposed to meet the safety requirement. In order to detect the characteristics of the magnetic memory signal of the wheelset or axle in real-time, the research on the force-magnetic effect of the wheelset or axle material is necessary. This paper takes 25CrMo4 as an example to analyze the relationship between the force and the magnetic. The experimental results show that the magnetic memory signal has a tendency to become smaller with the increase of the load on the experimental specimens.
