TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 3, TAPE TDOP 0086

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-60 ft. 100 Ton Box* Truck-Bosber S2C* Truck Center-46 Ft. 3 In.* Load-Full* Wheel Profile-New 1 in 20* Spring Group 7-D5O; 7-D5I* Snubbing-8-B432;8-B433* 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-030201CNE001* Track-Curved* Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear* Additional Experimental Conditions-None* Errors noted-Ch. 47 and 13 pos. off 0 ***FILE 2: Name-030201CNR001* Track-Curved* Speed-20mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 3: Name-030201CNO001* Track-Curved* Speed-35 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch. 27 reversed through MP 32.5; ch 47 neg noise.
