TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 3, TAPE TDOP 0107

The 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-89 Ft. Flat Car* Truck-ASF Low Level* Truck Center-64 Ft. 0 In.* Load-Full* Wheel Profile-New 1 in 20* Spring Group 5-D4 O; 5-D3 I* Snubbing-8-3221; 8-3222* 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-030502TSR002* Track-Med.Spd.Jtd.* Speed-26 to 34 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-030502TWA002* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch. 21 -0.9 V off 0.
