Increasing coupling properties of locomotive by magnetizing contact area of wheel with rail

The authors of the paper consider a section of the magnetic circuit, which includes a band of a wheel pair, a railhead and an air gap between them. The parameters of the magnetic field and magnetic resistance between the wheel and the rail are obtained. Attention is paid to the decrease in the magne...

Description
Summary:The authors of the paper consider a section of the magnetic circuit, which includes a band of a wheel pair, a railhead and an air gap between them. The parameters of the magnetic field and magnetic resistance between the wheel and the rail are obtained. Attention is paid to the decrease in the magnetic permeability of saturated steel regions and to the change in the magnetic susceptibility of the contact regions at high temperatures in the contact spot. The epicenters of the magnetic field concentration at different modes of magnetization are determined taking into account the change in the wheel position relative to the rail.
