Abstract

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
The locomotive coupler usually adopts semi-permanent non-compact coupler, which has the characteristics of strong yaw attitude compared with the compact coupler of urban railway. The state of the coupler has an extremely strong randomness in influencing ...
