TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 1, TAPE TDOP 0038

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 7-05 O; 6-05 I* 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-010206TEM001* Track-Hi.Spd.CWR* Speed-30 to 60 in 10 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch 23 no neg., ch 17, 20, 25, Off 0 ***FILE 2: Name-010206TEH001* Track-Hi.Spd.CWR* Speed-70 and 79 mph* Outer Gib Clearance-1/4 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch 23 no neg. ***FILE 3: Name-010206TEM001* Track-Med.Spd.Jtd.* Speed-15 to 45 in 5 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch 23 no neg., ch 22 + .2V off 0 ***FILE 4: Name-010206TSR001* Track-Med.Spd.Jtd.* Speed-24 to 32 in 2 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch 43 inop., ch 23 no neg.
