PERFORMANCE TESTS OF LONG TRAVEL CUSHION UNDERFRAMES

The concept developed in the past few years that cushion travel of at least 20 in. and preferably 30 in. is required for lading protection at impact speeds of 10 mph or more and the confirmation of this in actual practice has led to the need for further investigation of the phenomena associated with this longer range of cushion travel. In 1962 it was decided to evaluate experimentally the order of difference to be expected from sliding center-sill cars having sill travel of 20 in. and sill travel of 30 in. Also, the possibility of developing new criteria for judging the comparative performance of freight cars during impact was to be studied. The results of this investigation are reported in the paper.
