Sinusoidal Calibration of Force Transducers Using Electrodynamic Shaker Systems

The primary calibration of force transducers using sinusoidal excitations with electrodynamic shaker systems will be described. First a view comment concerning the importance of dynamic force measurements will be given. That will be followed by a mathematical description of the basics of dynamic measurements based on linear differential equations. Some useful approximations are given to average measured data. The technical equipment will be introduced together with a discussion concerning the traceability as well as the uncertainty consideration. Finally, exemplary a calibrations performed on a strain gauge force transducer will be presented. Copyright © 2012 IFSA.
