摘要Monitoring the wheel-rail adhesion state and maintaining the stability are the key issues to ensure the safety of locomotives with increasing running speed nowadays. In this paper; a novel methodology is proposed to determine the wheel-rail adhesion stability. It is proved that when the adhesion state is in the unstable region, the transmitting factor which is defined as the ratio of the adhesion force in the wheel drive force is negative. Based on this principle, we propose a novel adhesion stability detector via measuring the wheel drive torque and the wheel rotational speed. It is five from measuring or determining the chassis speed, creep ratio, and optimal creep ratio, which are usually difficult to obtain in practical applications. In addition, the proposed methodology can evaluate the adhesion state dynamically regardless of the specific wheel-rail conditions. Numerical simulations are carried out to validate its effectiveness.
