Shear Mechanical Characteristics and Density Dependence ofAnnular Metal Rubber Damper

The movement characteristics of curved beam of annular metal rubber damper under the tangential and axial shear were analyzed by LS-DYNA software based on the fabrication process, shear test machining design, damping energy characterization methods of annular metal rubber damper, and simplified the three-dimensional numerical model. The shear mechanical characteristics and density dependence of annular metal rubber damper were studied. The results show that sliding mode among most of wire curved beams was parallel slipping in the metal rubber damper. With increasing density, the energy dissipation coefficient of annular metal rubber damper in tangential and axial shear increased first and then decreased, and the equivalent stiffness increased.
