摘要
提出了一种不漏液新型双向剪切型黏滞阻尼器,对黏滞液黏温性能、阻尼器力学性能进行了试验研究,得出阻尼力计算公式。研究结果表明,双向剪切型阻尼器出力大,导轨副对阻尼器的水平性能影响较大,采用固体Kelvin模型可较好地模拟阻尼器的本构关系。
A new non-leakage bidirectional shear-type viscous damper is proposed.Experimental studies on the viscous fluid's viscosity-temperature performance and the mechanical performance of the damper were conducted,resulting in a formula for calculating the damping force.The research results indicate that the bidirectional shear-type damper has a high output,the horizontal performance of the damper is significantly affected by the guide rail pair,and using a solid Kelvin model can adequately simulate the constitutive parameters of the damper.
