Abstract
Suppression of slip and reduction of friction between rail and wheel are important in railway systems. This paper proposes a novel slip re-adhesion control based on the excessive torque and excessive angular momentum for 4 axle and 2 truck model (1C2M, 1 inverter 2 motor drive system). Effectiveness of the proposed method has been confirmed by mathmatical analysis. Furthermore, the proposed method was evaluated by two performance indicators, frictional force reduction and effective utilization of adhesive force. As a result, adhesion characteristic of the proposal method was 7.04 % better than the conventional method. In addition, loss friction force around driving wheel remained unchanged.
