Abstract :
This research is concerned with weighing the behavior of the front end
energy absorption system of a locally manufactured locomotive in crash
situations. The causes of the extensive damages to the energy absorption
apparatus that includes the crash element and the buffer are studied. By
choosing the proper damage model the conditions of the accident is
simulated by using the ABAQUS engineering software. The amount of the
absorbed energy during a crash is estimated. Improvement of the existing
mechanism is also considered. A metal honeycomb energy absorber is
proposed to increase the energy absorption capacity of the locomotive front
end.
