THEORETICAL STUDY OF MECHANICAL IMPEDANCE ON THE HUMAN HAND-ARM SYSTEM
This article is a processing of the informations found in specialized literature and international standards about evaluating the vibrations of the portable machine-tools and their action on the human hand-arm system by modifying its mechanical impedance. Emphasis was placed on establishing the importance of mechanical impedance measurement in the study of the action of the vibrations on the human body and on the way it is calculated for various purpose-built mechanical models.Key words: mechanical impedance, vibration, hand-arm system, impedance measurement.
