Measurement Problems Associated with the Study of Segmental Vibration.
NIOSH 1977 Apr:169-172
Attempts to measure segmental vibration are discussed as well as the problems encountered. Since actual physical measurements are important to the study of shock and vibration response of the users of hand-held power tools, and accurate set of acceleration readings at typical input amplitudes and frequencies would aid in determining the vibration absorption characteristics of the hand and arm, and possibly lead to changes in power tool design. It is difficult to measure vibration of a power tool under various loading conditions. Response of the hand and arm is even more difficult to measure with any degree of precision. Limited studies of force transmission through the hand-arm system have been made by mounting accelerometers on bands tightly attached to the arm. In cadaver studies, accelerometers have been mounted directly on the humerus, radius, and ulna (of an arm severed at the shoulder and excited at the hand). In addition, the dynamic mass, spring constant, and damping of the hand-arm system have been determined by using a shaker with an impedance head.
