Abstract. An improved set-up for the characterization of multi-component sensors for force and moment is presented. It aims at calibrating such sensors under continuous sinusoidal excitation. Special focus is put on the design of load masses and adapting elements to activate uniaxial force and moment components where possible. To identify the motion and acceleration of the load mass with 6 degrees of freedom, a photogrammetric measurement system is implemented in the existing set-up. Using the set-up described, different experiments are performed to analyse a commercial multi-component sensor and perform a parameter identification for its force components.

Short summary
Multi-component sensors for force and moment are commonly used in different areas as robotics, crash tests or material testing. The dynamic behaviour of such sensors may differ significantly from the static behaviour. To analyse the dynamic characteristics, we developed an improved test set-up for periodic excitation. It consists of an electrodynamic shaker, adapting elements and different acceleration references. The first experiments show good results for periodic excitation up to 1000 Hz.
