ADAPTIVE MRE VIBRATION ISOLATION ASSEMBLY AND SYSTEM

摘要

A vibration isolation assembly (12)includes a top plate (18) adapted for connection to the first body, and a bottom plate (15) adapted for connection to the second body. A vibration damping core (20) is disposed between the top plate and the bottom plate. The core includes a plurality of damping layers (21) formed from an MRE material having variable damping characteristics responsive to variation in strength of an applied magnetic field, and a plurality of support layers (22) interposed respectively between the damping layers to form a laminated central core section. An electromagnetic coil (30) extends around the core to generate a magnetic field of variable strength passing generally axially through the core. A yoke (32) extends generally around the coil. The assembly is adapted to provide adaptively controllable damping of relative vibrational displacement between the first and second bodies.
