FREIGHT CAR TRUCK DESIGN OPTIMIZATION. VOLUME VIII. RESULTS REPORT FOR TEST SERIES 2 AND 5

This results report contains information reduced from the Truck Design Optimization Project (TDOP) data tapes and organized into an appropriate graphical output. These results encompass data from Test Series 2 and data from the 70-ton (63.6-mt) mechanical refrigerator car used in Test Series 5. Test Series 5 also included data from a 100-ton (90.9-mt) boxcar on cylindrical profile wheels with spring variations and snubbing supplements. These results will be reported with other 100-ton (90.9-mt) boxcar data in Test Series 3 Results Report. In this report, results from Test Series 2 and 5 are compared with the base case results described in TDOP Results Report For Series 1 Tests. Testing was expanded in Series 5 to evaluate harmonic roll characteristics on a specially prepared track, and the results from these tests are used to establish a base case for harmonic roll characteristics.
