| 摘要： | All new tactical vehicles and aircraft are required to be evaluated for potential whole-body vibration (WBV) health hazards to their crewmembers. A health hazard assessment (HHA) was performed on the M916Al 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 M916A1 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 were experienced on the Belgian block course, with less severe WBV occurring on the cross-country course, followed by the primary terrain course. The results also show the passenger exposure limits were consistently lower than the driver's. Therefore, the HHA recommendation for the M916A1, operating in its intended environment, is that WBV be limited to the following passenger exposure limits for each test condition: WBV is not to exceed 17.1 hours in any 24-hour period on paved surfaces for all configurations.
