The present application relates to a kind of magnetorheological disc
type metal rubber adjustable damping stiffness
damper structures, including
damper body and the damping core shaft being arranged in the middle of
damper body, working cavity is arranged in the inside of damper body, disc
type metal rubber is equipped between the working cavity inner wall and damping core shaft, disc
type metal rubber inside is limited by
metal rubber mounting end cap, disc type
metal rubber outside can be positioned and pre-tightened using different inner
diameter installation
gasket disc,
magnetorheological fluid is arranged in working cavity, and the side of damper body is provided with
electromagnetic coil.The present application changes the equivalent constraint of disc type
metal rubber by installation
gasket disc,
metal rubber mounting end cap and other structural parameters, realizes the structural adjustment of stiffness on the one hand;On the other hand, the yield stress and
apparent viscosity of
magnetorheological fluid are regulated using external
magnetic field, change its flow resistance in
metal rubber pore channel, realize damping force on-line adjustable, so that more optimal
vibration isolation matching is obtained under different load and vibration conditions.
