摘要

本文依据扇形铅粘弹性阻尼器组成材料的特性,给出了阻尼器的构造参数与恢复力学模型之间的关系,推导出该阻尼器恢复力模型公式,给出了阻尼器的设计方法。基于扇形铅粘弹性阻尼器的性能试验结果,对比分析了理论推导结果与试验结果,分析结果表明:扇形铅粘弹性阻尼器的力学性能主要取决于橡胶和铅芯两种材料,可用双线性恢复力学模型对其进行描述;该阻尼器滞回曲线及设计值与试验值吻合度较好,推导的恢复力模型公式合理可行。

Abstract

Based on the materials characteristics of the sector lead viscoelastic dampers(SLVD), the relationship between appropriate structural parameters and restoring force model was given, and the restoring force model of SLVD was investigated. The design method of the damper was given. The performances of the damper were tested under low frequency cyclic load. The results were compared with the numerical simulation and the test. The investigation results indicate that: the mechanical properties of the sector lead viscoelastic damper are mainly depended on rubber and lead; the symmetric bilinear model can be used to describe the restoring force model of the damper. The experimental and numerical simulation results of SLVD hysteretic curve have a well agreement, it is feasible to adopt the given model to simulate the damper element.
