Analytical modelling of electrorheological material based adaptive shells

Electrorheological fluids show immediate variations of their rheological properties when subjected to varying electric fields. This study presents vibration analysis of a closed cylindrical shell partially filled with controllable fluids. The analysed structure as an element of harmonic drive can generate torsional vibration due to the wave generator operation. As a result of the study, fluid-filled laminated cylindrical shell has shown an increased aud controllable damping capacity as compared to the conventional shell.
