    Shear Mechanical Characteristics and Density Dependence ofAnnular Metal Rubber Damper

    • 摘要: 基于金属橡胶阻尼环的制备工艺流程、剪切试验工装设计以及阻尼耗能表征方法,通过建立金属橡胶阻尼环简化三维数值模型,采用LS-DYNA软件分析了金属橡胶阻尼环在切向和轴向剪切位移下的曲梁运动特性,研究了金属橡胶阻尼环的剪切力学特性及其密度相关性。结果表明:金属橡胶阻尼环的金属丝曲梁之间的滑移方式多为平行滑移;随着密度的增大,金属橡胶阻尼环的切向和轴向剪切能量耗散系数均先增大后减小,等效刚度均增大。

       

      Abstract: 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.
