Abstract: The characteristics and existing problems of ISO standard 2631 and absorbed power method, which are the currently most popular methods for evaluating human exposure to whole-body vibration in automotive ride, are discussed in detail. The theoretical analysis based on an automotive mechanics model as well as experimental results shows that GB 4970-85, which is based on ISO standard 2631, cannot accurately evaluate human exposure to whole-body vibration in automotive ride. Therefore, this paper develops a new evaluating method, using the accumulated exposure times within the frequently used speeds to evaluate human exposure to whole-body vibration of automotive ride. The evaluation result obtained with this newmethod coincides with the facts well.
