Dynamic tuning of torsional transmissibility using magnetorheological elastomer: Modelling and experimental verification

Mechanical systems with rotary machines or rotating elements experience torsional vibration, which may lead to an extreme damage and wear. Conventionally, to isolate these undesirable structural vibrations, passive elastomer or torsional dampers are used. However, these passive vibration isolat...
