摘要
介绍一种新型的斜拉桥拉索用粘性剪切型阻尼器 ,并给出了该阻尼器的设计原理和方法。采用动力试验方法对其减振性能及减振规律进行了室内及实桥试验研究 ,并对试验结果进行了分析。研究表明 ,这种阻尼器减振性能优良 ,完全可用于实桥拉索的振动控制。
A new type of vicious shear damper used in the cable stayed bridge is introduced and its design method is given.Dynamic experiment is used to study the performance and rules of \{reducing\} vibration of cables damper system in doors and in the field. The experimental results are analyzed. It shows that this kind of damper has excellent performance in reducing vibration of \{cables from \}the experiment.It can be used in vibration control of cables of the \{cable stayed\} bridge.
