Whole-Body Vibration Assessment of the M1070 Heavy Equipment Transporter. Volume 1

An evaluation of all new tactical vehicles and aircraft is required to assess potential whole-body vibration WBV health hazards to crewmembers. As requested by the U.S. Army Environmental Hygiene Agency USAEHA, a health hazard assessment HHA was performed by the U.S. Army Aeromedical Research Laboratory USAARL on the M1070 Heavy Equipment Transporter System HETS. The HETS was tested on three cross-country courses at Aberdeen Proving Ground APG, MD, by the U.S. Army Combat Systems Test Activity USACSTA, in coordination with the Response and Tolerance Branch of USAARL. The M1070 HETS was tested with a M1000 trailer in a loaded and unloaded configuration. The loaded configuration was obtained by placing an M1 tank on the bed of the M1000 trailer. The unloaded configuration consisted of a M1070 tractor with an empty M1000 trailer. While operating the HETS in its intended operational environment, the front passenger was exposed to an overall risk assessment code of 5. This consisted of an overall assignment of hazard severity category IV and hazard probability level D.
