摘要

提出一种新型的剪切型铅阻尼器，该装置中铅块直接嵌于滑动钢板与固定钢板的凹槽之间，构造简单。基于性能试验和有限元分析对该装置的滞回性能及关键参数进行了研究，研究结果表明：该阻尼器的滞回性能可以采用双线性模型加以模拟；阻尼器屈服阻尼力由铅块的剪切面积决定；加载曲线中弹性阶段与完全塑性阶段之间的过渡弧段的曲率半径与剪切铅块的长厚比成反比。

Abstract

a new type of shear lead damper is presented herein. For this new device,the moving steel plate and the fixing plates need to be grooved, and the shear lead block can be embedded exactly in the room between moving and fixing plates when these plates are overlaped without spacing and locked by bolts. Parameters studies have been done on the basis of finite element analysis and performance tests. Some conclusion can be drawn: the hysteretic performances of this damper can be modeled by bilinear mode; the yield force of this damper is determined mainly by the shear area of lead block; the ratio of length to thickness of shear lead block will impact the curvature radius of arc segment between elastic stage and plastic stage.
