Abstract: Aiming at the problem of translational and torsional vibration of the eccentric structure under earthquake, the control effect of magnetorheological elastomer damper on translational and torsional vibration of the eccentric workshop structure is studied. Firstly, the mechanical model of magnetorheological elastomer damper and a finite element model of the structure are established. Then, the finite element simulation is utilised to analyse the damping effect of the damper on the structure. The analysis results show that the damping effect of the damper on the translational vibration of the eighth layer of the structure is 43.27%, and the damping effect on the torsional response of the fifth layer is 37.37%. Finally, a shaking table test is done. The test results show that when the damper acts, the translational displacement of the top layer of the structure decreases by 34.97%, and the torsional response of the fifth layer of the structure reduces by 41.58%.

Keywords: eccentric workshop; magnetorheological elastomer damper; mechanics model; shaking table test; damping effect.
