Novel magnetic rigidity-variable inerter shock absorber
The invention discloses a novel magnetic variable-rigidity inerter damper which comprises an upper top plate, a lower bottom plate, a ball screw, a ball nut and a magnet assembly. The upper end of the ball screw is connected with the upper top plate in a fastened mode. The magnet assembly comprises a sliding magnet and a U-shaped magnet. The lower end of the ball screw is fixedly connected with the sliding magnet. The lower bottom plate is provided with the supporting assembly, the U-shaped magnet is horizontally installed on the supporting assembly, the annular copper core is installed between the S pole and the N pole of the U-shaped magnet, the annular copper core is installed on the supporting assembly through the ball guide rail, and the ball nut is installed on the annular copper core in a fastening mode. The lower bottom plate is fixedly provided with a silicon steel iron core located under the sliding magnet, the silicon steel iron core is wrapped by a coil winding, the supporting assembly is provided with a carbon brush in sliding contact with the annular copper core, and a middle connecting wire between the coil winding and the carbon brush is provided with a full-bridge rectifier. The shock absorber has the advantages of being novel in structural design, good in shock absorption and energy dissipation effect, capable of achieving rigidity adaptive adjustment and change and good in stability and reliability.
