Shock and vibration data acquisition system for off-road vehicle operator health and safety assessment
2006
A data acquisition software and hardware system was developed for acquiring
geo-referenced shock and vibration data using National Instruments’ LabView graphical
programming language. This was used in conjunction with a modular data acquisition and
signal conditioning system and a Differential Global Positioning System (DGPS) receiver. A
prototype vehicle obstacle course, which introduced spatially varying shock events to vehicles
as they traversed the course, was constructed. Obstacles consisted of both repetitious and
single discrete events. A series of investigations was conducted on the obstacle course to
evaluate the performance and characteristics of the DAQ system and the tractor when exposed
to shock and vibration events. Spectral and time domain plots obtained from the
geo-referenced data acquisition system (GDAQ) system under static, highway, and off-road
obstacle course conditions were evaluated to demonstrate that the system performed as
expected. The migration of experiments from laboratory to field gave confidence that this
system could be used to collect shock and vibration data over a wide range of frequencies. The
use of geo-referenced data records proved beneficial in isolating and extracting data
segments of interest from a continuous data record.
