Instrumentation of Navistar Truck for Data Collection

Status:  Complete
Report Date:  01/15/2013


The overarching goal of this project was to instrument the new MnDOT Navistar truck used at MnROAD. A rugged data acquisition, data recording and wireless transmission system was established for collection of various sensor signals from the truck. The truck was instrumented with a suite of 20 accelerometers, with these accelerometers being located both on the five axles of the truck and on the tractor and trailer bodies. In addition, the truck was instrumented with a differential GPS system and an inertial measurement unit in the tractor cab. A cRIO-based data acquisition system, a rugged laptop and Labview software together serve as a flexible platform for data acquisition. The above instrumentation of the truck will enable data collection on truck vibrations, enable analysis of correlations between truck vibrations and variations in signals of weigh-in-motion sensors, and enable recording of truck movements and pavement loads at MnROAD.
