Evaluation of Skid Test Automatic Digital Recording System

Report No: 75-R511

Published in 1974

About the report:

The Virginia skid vehicle has been equipped with a digital data recording system to provide rapid reduction of skid measurement data. It was found that five to ten minutes are required to evaluate a single measurement using the original analog strip chart system, whereas the digital results for a full day of testing can be evaluated within a matter of minutes. The components of the recording system and the calibration and measurement procedures were examined, and the results from the digital system were studied to determine their precision and accuracy as compared to the analog system results.
