TEST CONDUCTED BY GENERAL MOTORS PROVING GROUNDS NOISE AND VIBRATION LABORATORY, REPORT NO. 22050

The objective of this test was to obtain data during a typical tri-level shipment known to cause automobile frame damage. The rail car chosen was NIFX-13551 which was a split deck, low tri-pack car with side cushions. The top level, front auto position was chosen as the location for the automobile because of a high failure rate among autos shipped in this position. The "T" hook, was used and standard tie-down procedure was followed in securing the automobile to the rail car. The instrument car was coupled directly to the tri-level rail car containing the test automobile. Large strains were recorded on a number of gages immediately after tie-down. Strains greater than 1500 KE generally result in yielding of the material for the type of steel used in automobile frames. The value was exceeded at each tie-down hole on initial tie-down.
