黏滞流体阻尼器性能试验研究

The Analysis of viscous damper for Performance Experience

非线性黏滞阻尼器因具有饱满的耗能滞回曲线,且不提供附加刚度而越来越受到抗震人员的青睐,但由于阻尼器的结构及耗能材料的选择对非线性黏滞阻尼器的性能影响较大,这也成为制约阻尼器生产的一大问题。为进一步了解阻尼器的各项性能,对国内某公司生产的黏滞流体阻尼器进行了性能试验研究,主要包括阻尼器的动力耗能性能、温度相关性能、频率相关性能、耐久性能等。这些试验数据也为后续非线性黏滞阻尼器的研究提供依据。

Seismic engineers have been favor of the nonlinear viscous damper,for its full hysteretic curve of energy consumption and providing no additional stiffness to the structures.But the selection of dissipation materials and the structure of the damper have the big influence on the performance of the damper.And they become the major problem to the production of the damper.In this paper,we do the performance experience of the dampers produced by a domestic company to study the further performance of the damper.The performance experiences include the power dissipation characteristics,temperature performance,frequency-dependent,durable performance,etc. These test data also provide the reference to the subsequent study on the nonlinear viscous damper.
