主　　题：Noise Whole-body vibration Vibration dose value Viking military vehicle 

摘      要：Noise and whole-body vibration measurements were made in a Viking military vehicle to determine the variation that should be expected during repeat measures,the effect of speed(up to 60 km/h in 5 km/h increments),and during travel over different types of terrain(comprising concrete road,gravel track and rough cross-country).Measurements were made at various crew positions(including the driver and commander)in both the front and the rear cabs in the *** translational axes of vibration were measured in each *** speeds were investigated over road(35 km/h and 55e60 km/h)and gravel(20 km/h and 35 km/h)*** effect of varying speed of the vehicle on the measured noise and vibration magnitudes was also *** highest sound pressure level(LAeq)of 104 dB(A)was measured at the commander’s standing position during travel over concrete road at 55 km/*** noise levels occurred for a standing commander compared with when sitting on the seat.A maximum single axis frequency-weighted vibration magnitude of 1.0 m/s^(2) *** measured on the driver’s seat during travel over track at 35 km/*** vibration magnitudes occurred during travel over track compared with travel over *** noise and vibration exposure of crew within the Viking vehicle increased with increasing speed of the vehicle.
