Abstract
In this paper, ways to establish dynamic calibration methods for force transducers are discussed. Three methods of evaluating the dynamic response of force transducers against typical varying forces, such as impact, oscillation, and step forces, are described in this paper. In all the three methods, the inertial force of a mass is used as the known dynamic force, and this reference force is applied to a force transducer under test. The inertial force is highly accurately measured as the product of mass and acceleration. An aerostatic linear bearing is used to obtain linear motion with sufficiently small friction acting on the mass (i.e., the moving part of the bearing). The present status and the future prospects of attempts toward establishing dynamic calibration methods for force transducers are discussed in detail.
