Abstract

Restricted by the properties of viscoelastic materials, the energy dissipation capability of traditional viscoelastic dampers is poor, resulting in the need to use a larger number of dampers to achieve a certain damping effect in practical engineering. In this paper, a new viscoelastic material was developed. The damping properties of viscoelastic material were improved by adding special damping material into natural rubber. Firstly, the shear properties of the new high damping viscoelastic damper full-scale specimens made of this material were tested, and the shear mechanical properties of the damper were investigated. Secondly, through basic mechanical properties tests of the scale specimen under different conditions, the variation of mechanical performance parameter of the damper such as equivalent damping ratio and equivalent shear modulus were studied. Further, in order to accurately simulate the mechanical properties of the damper, the nonlinear four-element constitutive model is established, and the parameters in the model are identified by multi-step relaxation test and fast shear test. Finally, the engineering application research of the vibration control effect of the damper is carried out. Research results show that the new high damping viscoelastic damper has excellent energy dissipation performance, and its mechanical properties remain stable under large shear strain; The mechanical properties of the damper are strain dependent and the loading frequency has little influence on its performance; The nonlinear four-element constitutive model can accurately simulate the shear mechanical properties of the damper; engineering application analysis results show that the new high-damping viscoelastic damper has a good vibration control effect.
