摘要：
The aim of this study is to explore the influence of magnetic field and surface roughness on the adhesion coefficient of wheel/rail using a JD-1 wheel/rail simulation facility. The results indicate that the magnetic field has a significant influence on the adhesion coefficient under the water and oil conditions by means of magnetic force on the wheel/rail contact zone. The use of magnetic field is beneficial to increase the adhesion coefficient of wheel/rail interface. The speed has no visible effect on adhesion coefficient under the magnetic field condition. Increasing surface roughness improves the adhesion level of wheel/rail interface under the water and oil conditions.
