Abstract

Viscoelastic (VE) dampers are a kind of effective passive vibration control device and widely used to attenuate structural vibration. In this article, experimental study and multiscale modeling analysis on the VE damper for reducing wind-excited vibration are carried out. First, an experimental study on VE damper is conducted to reveal the dynamic properties of VE damper. The experimental results show that the dynamic properties of VE material are influenced by excitation frequency and insignificantly affected by displacement amplitude, and the VE material has good energy dissipation capacity. Second, the damping mechanism of VE damper is analyzed from micro-perspectives by considering the influence of cross-linked and free molecular chain networks. Then, a novel type spherical chain network model based on the chain network microstructure is proposed. The proposed model is verified by comparing the experimental data and the mathematical results, which indicates that the proposed model can accurately describe the dynamic properties of VE damper affected by different temperatures, frequencies, and displacements.
考虑基体橡胶/炭黑界面效应的粘弹性阻尼器实验与建模研究
粘弹性阻尼器是一种有效的被动振动控制装置,广泛应用于结构振动的衰减。本文对VE减振风激阻尼器进行了实验研究和多尺度建模分析。首先,对VE阻尼器进行了实验研究,揭示了VE阻尼器的动力特性。实验结果表明,VE材料的动态性能受激励频率的影响较大,受位移幅值的影响不显著,具有良好的耗能能力。其次,考虑交联和自由分子链网络的影响,从微观角度分析VE阻尼器的阻尼机理。在此基础上,提出了一种基于链网微观结构的新型球形链网模型。通过实验数据与数学结果的对比,验证了所提模型的正确性,表明所提模型能较准确地描述不同温度、频率和位移对VE阻尼器动态特性的影响。
