Research Abstract	The objective of this study was to develop an evaluation and prediction method of subjective responses of people exposed to whole-body vibration based on their dynamic responses. Experiments involving human subjects were conducted to understand the relation between dynamic responses and discomfort caused by vibration in the vertical and the horizontal directions, respectively. A mathematical model to predict the dynamic response of the human body was then developed so that the evaluation of vibration discomfort could be made based on dynamic responses predicted for any input motions.
