TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 4, TAPE TDOP 0166
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-Full* Wheel Profile-New 1 in 20* Spring Group 7-D5O; 6-D5I* Snubbing-8-9031* Snubber Augmentation-None* Centerplate Friction-Steel-Steel* Additional Experimental Devices or Conditions-Constant contact side bearings; Long. Adapter clear. is 0; Long. Controls under axles* 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-040501CNE001* Track-Curved* Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-Ch. 34 noisy ***FILE 2: Name-040501CNR001* Track-Curved* Speed-18 mph* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-Ch. 30+0.4v. off 0; Ch. 10-0.2V. off 0 ***FILE 3: Name-040501CNO001* Track-Curved* Speed-35 mph* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-None.
