【Abstract】 Aiming at the problem of insufficient adhesive force between the wheels and rails of high-speed trains, this paper proposes a wheel-rail adhesion increasing device based on the electromagnetic mechanism to improve the adhesive relationship between the wheels and rails. The basic structure and adhesion increasing mechanism of the device are presented and analyzed. The magnetization effect, magnetic-thermal coupling and alternating degaussing are simulated, and a comprehensive evaluation index is derived to quantify the adhesion increasing effect and self-performance of the wheel-rail adhesion increasing device.更多还原
