The invention relates to a variable rigidity shock insulation integral intelligent support seat and belongs to the technical field of building structure shock absorption. The variable rigidity shock insulation integral intelligent support seat is characterized by comprising an upper connecting plate (1), a lower connecting plate (4), a magnetic conduction steel plate (2), a magnetorheological elastic body (3), an
excitation coil (5), a magnetic conduction iron core (6), a
polymer matrix composite permanent
magnet material (7), a lead core (8), a conducting wire passage (9), an upper connecting screw bolt hole (10), a lower connecting screw bolt hole (11) and a driving power supply (12), wherein the a magnetorheological elastic body (3) and the magnetic conduction steel plate (2) are in a circular ring shape or a square ring shape, the
excitation coil (5) and the magnetic conduction iron core (6) are arranged inside a support seat, and the
polymer matrix composite permanent
magnet material (7) provides a bias
magnetic field for a closed
magnetic circuit. The variable rigidity shock insulation integral intelligent support seat has the effects and benefits that the shock insulation and the variable rigidity are integrated, the structure is simple, the anti-interference performance is high, the two-way rigidity regulation can be realized, different horizontal rigidities can be provided for the structure according to different quake
waves, and the destroy of earthquake disasters on building structures and bridge structures is effectively reduced.
