摘 要: 采用ABAQUS软件对高阻尼黏弹性阻尼器进行有限元数值模拟分析,研究不同应变幅值对其力学性能及应力分布的影响。分析结果表明,高阻尼黏弹性阻尼器在小应变下即开始耗能,随着应变幅值的增大,其滞回环面积及各项力学性能相应增大;黏弹性材料层在剪切耗能过程中的应力分布由外侧向内侧增大,在内侧边缘处达到极大值。
关 键 词: 土木建筑结构;高阻尼;黏弹性阻尼器;数值模拟

Abstract: The influences of different strain amplitudes on the mechanical property and stress distribution of the high damping viscoelastic damper were investigated by conducting the numerical simulation finit element analysis with the aid of software ABAQUS. The result show that the high damping viscoelastic damper begin to consume energy at a small strain, the hysteresis loop area and the mechanical properties increase with the increase of the strain amplitude. The stress distribution of the viscoelastic material layer increases from the outside to the inside during the energy dissipation process, reaching the maximum value at the inner edge.
