Kurzbeschreibung (Abstract)
A test facility was designed to perform measurements of a specific electrorheological fluid in squeeze and shear mode. This device allows measuring the dynamic response of the fluid under various excitation conditions. Dense measurement grids at harmonic excitation are collected in dependency of the excitation frequency, the displacement amplitude and the applied electric field. Based on these measurement cycles, a material model for squeeze and shear mode is proposed and its corresponding model parameters are identified within this parameter space. The fitted model is benchmarked against the measurement data and is capable of resembling the fluid’s dynamic properties at harmonic excitation; including transitions between Bingham-like and visco-elastic material behavior. However, clear trends within the parameter space cannot be stated for all model parameters. This prevents the extension of the identification results to predict the fluid behaviour at transient excitation and is subject to ongoing research fostering the further developments of ERF-devices.
