Mechanical properties of single-layer and multi-layer amplified viscoelastic dampers
为提高黏弹型阻尼器耗能效率,结合杠杆位移放大装置设计了 3种放大型黏弹阻尼器,分别为单层放大型黏弹阻尼器、多层单向放大型黏弹阻尼器和多层双向放大型黏弹阻尼器.在线性Kelvin模型的基础上,提出了改进的非线性NLKelvin模型用于描述阻尼器的非线性力学特性,并建立了相应的力学模型.对单层放大型阻尼器与普通黏弹型阻尼器进行力学性能试验,试验结果表明:单层放大型阻尼器的阻尼力与耗能均得到了显著的提高,其阻尼力是普通阻尼器的5.41倍,耗能是普通阻尼…查看全部>>
To improve the energy dissipation efficiency of viscoelastic dampers,three kinds of amplified viscoelastic dampers were designed employing a lever displacement amplifier,namely,single-layer amplified viscoelastic damper,multilayer amplified viscoelastic damper and multilayer bidirectional amplified viscoelastic damper.On the basis of the linear Kelvin model,an improved nonlinear NLKelvin model was proposed to describe the nonlinear mechanical properties of t…查看全部>>
