COMPUTER ORIENTED DATA COLLECTION AND REDUCTION SYSTEM FOR ANALYSIS OF RAILROAD FREIGHT CAR TRUCK BEHAVIOR

The Truck Design Optimization Project has been conducting extensive field testing of conventional freight car trucks under various loadings, car types, track conditions, speeds, and a wide range of modifications. The data collection effort is controlled by a rail car-mounted minicomputer using interactive commands to guide the test crew in the entry of both alphanumeric descriptive data and the digitized values from 48 channels of accelerometers, displacement tranducers, and strain gages. These data are recorded on magnetic tapes which are processed at a large computer installation to produce both printed and mechanically-plotted graphical output for detailed analyses.
