TRUCK DESIGN OPTIMIZATION PROJECT FIELD TEST DATA, SERIES 5, TAPE TDOP 0199

The 2 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-100 T. 60 ft. Box* Truck-Barber S-2C* Truck Center-46 Ft. 3 In.* Load-None* Wheel Profile-Cylindrical* Spring Group 5-D5O; 5-D5I* Snubbing-8-B432;8-B433* Snubber Augmentation-Volute* 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. Side bearing forces are also questionable. Individual variations of the different tests are as follows: FILE 1: Name-050304MOD001* Track-Shimmed* Speed-22 to 30 in 2 mph steps* Outer Gib Clearance-5/8-In.* Side Bearings-1/4 In. Clear* Additional Experimental Conditions-None* Errors noted-Neg. noise on ch. 42 & 45***FILE 2: Name-050304TSM001* Track-Mod. Spd. Jtd.* Speed-15 to 45 in 5 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-None.
