TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 5, TAPE TDOP 0172

The 2 data files on this magnetic tape include acceleration, force, and displacement measurement at critical points on a freight car and truck. Each file includes detailed alphanumeric descriptions of test conditions. The following are for all tests on this tape: Car-70TonMReefer* Truck-ASF Ride Control* Truck Center-45Ft.9In.* Load-None* Wheel Profile-Cylindrical* Spring Group-7D3O;2-D3I* Snubbing-8-3091* Snubber Augmentation-None* Centerplate Friction-Steel Moly* Additional Experimental Devices or Conditions-None* NOTE: Vertical adapter forces are subject to question. Those on sharper curves or empty cars at high speed are least accurate. Individual variations of the different tests are as follows: FILE 1: Name-050104TWA001* Track-Hi.Spd.Htd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8In.* Side Bearings-1/4In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-050104TEA001* Track-Hi.Spd.CWR* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4In.Clear.* Additional Experimental Conditions-None* Errors noted-ch.10-0.5u off 0 on pass 2; ch. 27 was +1.0v off 0 on pass 2.
