Mass Measurement Using a Dynamic Vibration Absorber.
Takeshi Mizuno, Takeshi NEGISHI · TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C · 1999
New mass measurement systems using a dynamic vibration absorber are proposed, in which a mass to be measured is attached to the absorber mass. Such mass measurement systems are named as vibration type, and their measurement principles and characteristics are studied with their basic models. It is also pointed out that mass measurement systems using a dynamic vibration absorber can be classified in several ways, for example, according to the motion of a mass to be measured, the type of the absorber, the method of exciting vibration, etc. An apparatus with an active dynamic absorber and an inertial-mass type vibrator was developed for experimental study on vibration type mass measurement. Experimental results demonstrate the effectiveness of the proposed mass measurement method.
