The biodynamic responses of seated occupants exposed to whole‐body vibration have been mostly investigated in terms of apparent mass characteristics, which show negligible contributions due to exposure level. Considering that the severity of vibration exposure is related to the level and duration of exposure, the apparent mass responses cannot be used for assessment of the associated risks. Alternatively, the absorbed power characteristics of the seated vibration exposed occupants show strong dependence on the level of exposure. The measured data, expressed in terms of the vertical absorbed power, are analyzed to study the effects of sitting posture on the biodynamic response under whole‐body vertical vibration.
