| 摘 要： | 本文首先介绍了作用所开发的铅粘弹性阻尼器的构造与性能，并根据铅弹性险尼器的试验滞回曲线，采用双线性模型和双线怀－ＲＯ模型来描述其力学性能，最后根据试验结果进行两种模型的对比分析。分析表明：双线性－ＲＯ模型比双线性模型更能真实地描述铅粘弹性尼器的滞回耗能特性。

| Abstract: | In this paper, the composition and characteristic of the lead viscoelastic damper are introduced firstly, and according to the test hysteresis curve of the lead viscoelastic damper, the Hilinear model and the bilinear-Ramberg-osgood model are used to simulate the hysteresis energy dissipation ability. Finally, according to the test result, the comparison and analysis of the models are performed. The result shows that the bilinear-RO model is better than the bilinear model for simulating the hytseresis energy dissipation ability of the lead viscoelastic damper. |
