COMPUTER PREDICTIONS OF FREIGHT TRAIN SHOCK ACTIONS

Results obtained from a digital computer simulation of longitudinal train action are presented. The effects of running friction, draft gear springback, train position and train speed on a run-out shock are shown. Various modifications in the characteristics of friction draft gears are studied. The impact characteristics of hydraulic end-of-car cushioners are studied. Simulations study the effects of such hydraulic cushioners on train action. Some underlying mathematical considerations and the general characteristics of the computer simulation are given.
