Vibration acceleration magnitudes of hand-held tools and workpieces

Abstract

The magnitudes of the hand-transmitted vibration, 297 hand-held tools and workpieces were measured at workplaces. The tools were used mainly in construction and manufacturing industries. The current standard for the measurement of hand-transmitted vibration has been based on the frequency- weighted acceleration of dominant axis method). According to the proposal of ISO/CD5349-1), the results of measurements (462 points) were recalculated by the method of the frequency-weighted acceleration sum. There is 32% of difference in average value between the acceleration sum and the dominant axis method.
