TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 1, TAPE TDOP 0030

The 3 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-D5O; 6-D5I* 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-010204CNE001* Track-Curve* Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-3/8 In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-010204CNO001* Track-Curve* Speed-35 mph* Outer Gib Clearance-5/8 In.* Side Bearings-3/8 In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 3: Name-00206CNG001* Track-Curve* Speed 25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-21, 22, 28, 29, 31, all off 0.
