INVESTIGATION OF AUTOMOBILE CARRIER CARS

The report is concerned with the cause of progressives or fatigue failures in deck beams and posts of automobile carrier cars. Impact tests of cars were conducted to determine rack action present. Results are that stresses in decks and posts during loading were small compared to stresses present when cars were rolling. Stresses changed from tension to compression as the rack rolled sideways, as a result the racks acted as rigid frames to resist rolling induced forces.
