Abstract

When a wheel slip occurs on a certain axle or when re-adhesion control is executed, the tractive force of the wheel-slip axle changes, which causes pitching of the bogie and the carbody. As a result, a change occurs in the weight acting on other axles in adhesion status, and wheel slips are likely to be induced. We developed a control system designed to reduce the induction of wheel slips considering axle-weight changes caused by other wheel slips. To verify the effectiveness of the control method, we conducted a water spring wheel-slip test using an EH200-type DC electric locomotive.
