Semi-active tuned mass damper based on magnetorheological elastomers
The invention discloses a semi-active tuned mass damper based on magnetorheological elastomers, and relates to the field of dampers. The semi-active tuned mass damper based on the magnetorheological elastomers comprises a net rack formed by connecting a plurality of connecting rods and a plurality of damper bodies, wherein two ends of each damper body are connected with at least one connecting rod, each damper body comprises a sleeve, a sliding rod the two ends of which are connected with the inner walls of the two ends of the sleeve respectively, and a magnetic conducting sliding block which is slidably arranged on the sliding rod in a sleeving mode, each magnetic conducting sliding block is fixedly sleeved with two magnetic conducting stacked rings and a magnetic conducting cylinder the inner wall of which is connected with the outer walls of the two magnetic conducting stacked rings respectively, the outer wall of each magnetic conducting cylinder is connected with the inner wall of the corresponding sleeve, a coil located between the two magnetic conducting stacked rings is wound around the outer wall of each magnetic conducting sliding block, and each magnetic conducting stacked ring is formed by coaxially and alternately arranging and connecting a plurality of magnetic conducting rings and a plurality of annular magnetorheological elastomers. According to the semi-active tuned mass damper based on the magnetorheological elastomers, the vibration reduction frequency band is expanded, and vibration reduction can be conducted on the vibration mode with large modal contribution of a main body structure.
