摘要:
为有效提升传统阻尼器的减震性能,文中提出一种双调谐颗粒惯容系统(particle inertersystem,PIS)进一步发挥惯容系统的质量放大效应和阻尼放大效应提高阻尼器的减震控制性能,并实现轻质化减震控制。首先基于简谐激励分析了典型惯容系统C2的动力响应特性,并选取惯容系统C2与颗粒调谐质量阻尼器耦合共同实现震动控制效果;然后选用3条地震波作为外界激励,对附加PIS的单自由度结构进行数值仿真分析,将其与附加颗粒调谐质量阻尼器的结构性能作对比,发现双调谐颗粒惯容系统具有较好的减震控制效果,尤其是对均方根响应的控制。同时,以输入El Centro波为例,双调谐颗粒惯容系统能够减小阻尼器运行行程并实现轻质化设计,具有一定的实际工程应用价值。
Abstract:
In order to effectively improve the damping performance of traditional dampers, the double-tuned particle inerter system(PIS)is proposed in this paper, which introduces the inerter system into traditional particle tuned mass damper(PTMD). By virtue of the mass amplification effect and damping amplification effect of the inerter system, the damping control performance of the damper is improved, and the lightweight damping control is realized. Firstly, the dynamic response characteristics of three classic inerter systems are analyzed based on harmonic excitation. Then the inerter system C2 and particle tuned mass damper are coupled to realize the vibration control effect. Under the excitation of three seismic waves, the numerical simulation analysis of the single degree of freedom structure with PIS is carried out. Comparing it with particle tuned mass damper, it can be found that PIS has a better control performance, especially the root mean square response. At the same time, taking the input of El Centro wave as an example, PIS can reduce the relative displacement responses of the damper and realize the lightweight design, which is meaningful in the practical engineering application.
