Relation between dynamic and subjective responses of human subjects exposed to whole-body vibration and its application to the evaluation of vibration environment

本研究的目的是发展一种基于人体动态响应的全身振动主观反应评价和预测方法。通过人体实验，分别研究了垂直方向和水平方向振动引起的动态响应与不适感之间的关系。建立了预测人体动态响应的数学模型，根据对任意输入运动的动态响应预测，对振动不适进行评价。

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.
