TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 5, TAPE TDOP 0171

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-70TonMReefer* Truck-ASF Ride Control* Truck Center-45Ft.9In.* Load-None* Wheel Profile-Cylindrical* Spring Group-7-D3O;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-050104MOO001* Track-Shimmed* Speed-20 to 28 in 2 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-050104TSM001* Track-Mod.Spd.Jtd.* Speed 15 to 45 to 5 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 3: Name-050104TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1.4In.Clear* Additional Experimental Conditions-Reached only 77 mph use file 1 tape 0 1972 for this test* Errors noted-None.
