Abstract
Multi-Component Force-/Torque Transducers are used in applications where the direction of the force- and torque vectors as well as their magnitude are unknown and time-dependent such as robotics, flow measurement or nondestructive testing. In contrast to the measurement task the calibration of those Sensors is only done statically in most cases. When the measurands are getting closer to the sensors resonance frequency, the usage of static calibration factors leads to deviations in the measurement. A dynamic calibration can be used to identify the frequency responses of the sensor and is the basis for designing an appropriate filter that compensates these deviations. In this paper the dynamic properties of a
multi-component force-/torque transducer are investigated using a calibration system based on a voice-coil actuator which allows the application of force with different waveforms. The results of the measurements are compared with results of FEM calculations and results of a static calibration and a compensation filter is designed.
