UNCERTAINTY CONTRIBUTIONS IN SINUSOIDAL FORCE MEASUREMENT

Christian Schlegel, Gabriela Kiekenap, Rolf Kumme
Abstract:
This paper describes one of the uncertainty contributions which can be derived from sinusoidal force measurements. These measurements are based on the application of a scanning vibrometer and the use of triaxial accelerometers. The measuring of many acceleration points on the top mass of the transducer makes it possible to obtain acceleration distributions from which a standard deviation can be derived; the triaxial accelerometer allow the observance of certain effects, like rocking modes, or other problems related to specific excitation frequencies of the force transducer. Both measurements can be related to each other.
