EVALUATION OF TECHNICAL METHODS AS PREDICTORS OF DISCOMFORT FROM WHOLE-BODY VIBRATION IN WORK VEHICLES

This report focuses on acute effects from whole-body vibration. The emphasis is on technical measurement methods for the prediction of discomfort. It includes six studies directed towards vibration, which drivers of work vehicles are exposed to. All measurements were based on vibrations on the seat. The objective of Study A was to compare different technical measurement methods for the evaluation of discomfort from stationary vibration. The objective of Study B was to evaluate how discomfort from whole-body vibration varies with the duration for shorter events to two minutes. The objective of Study C was to compare different technical measurement methods for the evaluation of discomfort from non-stationary whole-body vibration. The objective of Study D was to review the literature concerning the time-dependency of effects from whole-body vibration. The objective of Study E was to evaluate the development of discomfort over a one-hour exposure to stationary whole-body vibration. The objective of Study F was to study discomfort and EMG, in the lower back and neck/shoulder during exposure to whole-body vibration and three different twisted postures. Some of the conclusions presented in this report were as follows; (1) frequency weighted analysis is better than one-third octave band analysis; and (2) the growth function of discomfort varies between different vibration frequencies.
