Whole-Body Vibration Assessment of the M915A2 Truck Tractor

摘要

All new tactical vehicles and aircraft are required to be evaluated for potentialwhole-body vibration (WBV) health hazards to their crewmembers. A health hazard assessment (HHA) was performed on the M915A2 truck tractor by the U.S. Army Aeromedical Research Laboratory, as requested by the U.S. Army Environmental Hygiene Agency. Tests were conducted at Aberdeen Proving Ground, Maryland, over paved surface, cross-country, and Belgian Block terrain types. The M915A2 was tested in bobtail (no trailer), unloaded, and loaded configurations for each of the test terrains. The results of these tests show the lowest tolerance levels, in general, were experienced on the cross-country course, with less severe WBV occurring on the Belgian Block course, followed by the primary terrain course.
