Actively controlled impact elements

摘要

A magnetorheological (MR) elastomeric composite (10) includes an elastomeric matrix material (11) and a plurality of MR elements (12) composed of a shaped MR material elastomer (14) with polarizable/magnetizable particles and at least one electrically conducting material (13) wound around at least one MR shaped material. The electrically conducting material-wound element is embedded in the elastomeric matrix material. The magnetorheological composite undergoes changes in modulus when the MR element is subjected to a magnetic field.
