MODERN CUSHIONING DEVICES FOR FREIGHT CARS AND THEIR EFFECT ON TRAIN ACTION
A mathematical prediction for dynamic braking forces is illustrated. The emergency braking of a train of 100 cars is used for the prediction. The roughest action is obtained when the train has been accelerated as rapidly as possible from a standstill just before the brake application. This action stretches out the train, closing or partially closing the draft gears. In this problem the solution was simplified by taking each group of ten cars as a unit. Thus, the 100-car train was reduced to a ten-car train. However, each one of these fictitous cars had the mass of the original ten cars it replaced. The draft gears on these cars had ten times the travel and ten times the capacity of the draft gears in the original cars. The solutions are illustrated for trains with and without standard draft gear and with hydraulic draft gear.
