Research on Dynamic Performance of Coupler for Rescue EMUs

摘要

In order to study the influence of train running parameters to the rescue electric multiple units (EMUs) coupler dynamic performance, a train–coupler system simulation model was established. The influence of different braking level, braking time and braking original speed to the longitudinal force and nodding angle of coupler during different types of multiple units after rescue coupled braking was researched. The result shows that the braking acceleration, braking time and vehicle grouping mode would have an influence on the dynamic performance of the coupler signally.
