Development of Re-adhesion Control Method Considering Axle-weight Transfer of Electric Locomotive

抄録

When a wheel slip occurs on a certain axle or when re-adhesion control is executed, the tractive effort of the wheel-slip axle changes, which causes pitching of the bogie and the carbody. As a result, weight on the other normally adhering axles changes, which may induce wheel slip.
This paper explains the development of a control system designed to reduce wheel slip induced by axle-weight changes caused by other wheel slips. To verify the effectiveness of the control method, a water spray wheel-slip test was conducted using an EH200-type DC electric locomotive.
