The impact of train sets is characterized by a very high potential for the longitudinal instability of the train resulting in overriding of the individual car-bodies. Consequently, the end-underframe structural mechanisms for crash energy management are not loaded and the train kinetic energy has ...
Preparations for a Train-to-Train Impact Test of Crash-Energy Management Passenger Rail Equipment coupler, energy absorbing elements, a crushable anti-climber to manage the interaction with the locomotive, and a cage for preserving the operator's space... D Tyrell,K Jacobsen,D Parent - IEEE 被...
The simulation results indicate that in some train collisions the maximal overriding speed can increase as large as 1.5 m/s. Under this condition, large constraint force and bending moment are induced and applied on the collided anti-climber, resulting in a serious vertical buckling. Besides that...
