TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 1, TAPE TDOP 0034

The 4 data files on this magnetic tape include acceleration, force, and displacement measurements 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-70 Ton M. Reefer* Truck-ASF Ride Control* Truck Center-45 Ft. 9 In.* Load-Empty* Wheel Profile-New 1 in 20* Spring Group 7-05O; 6-05I* 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-010204TEM001* Track-Hi. Spd. CWR* Speed-30 to 60 in 10 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-3/8 In. clear.* Additional Experimental Conditions-None* Errors noted-ch 23 no neg., ch 36, 39, and 46 questionable ***FILE 2: Name-010204TEH001* Track-Hi. Spd. CWR* Speed-70 and 79 mph* Outer Gib Clearance-1/4 In.* Side Bearings-3/8 In. clear.* Additional Experimental Conditions-None* Errors noted-ch 46 questionable calibration, ch 23 neg inoperative ***FILE 3: Name-010204TSR001* Track-Med. Spd.
