Industrial novelty dampers by development of advanced materials with high performance under electromagnetic rheological stimulation (IND-DAMPERS)

Ziel

The project addresses the distributing vibrations to man, machinery and structures for reasons of safety, comfort, reliability and for gaining a competitive edge, as it aims at developing a generic technology for the manufacture of purpose-oriented high-performance magnetorheological materials, and to demonstrate their validity through the design and construction of semi-active, real-time controllable dampers. When successful, these innovative systems could be widely used. These dampers require little energy to operate and are by definition fail-proof since in case of failure a passive component is always present. The work will encompass defining the semi-active requirements, proceed over numerical modeling and prototype development to a phase of up-scaling and performance validation.
