Attention decrease of drivers exposed to vibration from military vehicles when driving in terrain conditions
In this study, we analyzed the phenomenon of reduced attention for 11 subjects using a 6-degree-of-freedom synthetic vibration platform to simulate the vibration from terrain driving. Military vehicles are mainly used in terrain conditions, and drivers are exposed to whole-body vibrations for long periods of time. Drivers not only have trouble with comfort and health, they also suffer decreased attention. This decrease has a negative effect on driving. The vibration signal of a military vehicle on terrain is simulated using a synthetic vibration platform. Eleven subjects experienced these synthesized field-terrain vibratio...
