The Curving Behaviour of Heavy-Haul Locomotive Couplers

Abstract:

Article Preview

Two types of typical heavy-haul locomotive coupler models were presented, one is round-pin coupler with shoulder-limit, and another is flat-pin coupler with frictional tail pairs and stop-limit, both of them adapting nonlinear hysteresis buffer models. Utilizing a train model consists of 2 detailed locomotives and 1 simplified freight wagon, curving behaviour of different couplers were studied. The results show that, the actual curving behaviour of different couplers could be accurately simulated by the established coupler dynamics models. This paper will play a promoting role for analyzing actual heavy-haul locomotive running behaviours and safety.
