Mass measurement system with dual reaction-mass type actuators

摘要

A mass measurement system using two reaction-mass type actuators as a vibration generator and a vibration absorber were studied both theoretically and experimentally. In the system, a measurement object is attached to one reaction mass. The principles and features of the measurement system were described. An experimental apparatus was deveoped in which bimorph-type piezoelectric actuators were used to drive the masses. The experimental results demonstrated that the developed system could measure mass accurately.
