新型双向扭转型金属阻尼器的理论研究
Theory Rasearch on a New Type of Torsional Metal Damper
【摘要】 在地震作用下,合理安装阻尼器可以提高结构的抗震性,因此对于阻尼器的构造提出更高的要求,本文提出一种新型扭转型金属阻尼器。通过简单的构造,在地震作用下使金属扭转变形,利用铅可再结晶的特性,达到消耗地震能量的目的。对提出的新型阻尼器力学模型进行数值分析,证明本文设计的金属阻尼器具有良好的耗能性能。
【Abstract】 The anti-seismic performance of structure can be improved by installing damper properly.Therefore, higher requests are needed for the structure of damper.This paper proposed a new torsional type of metal damper. Through simple structure of the new damper,the energy created by earthquake can be consumed by the torsional deformation and re-crystaliztion of lead.By numerical analysis of the mechanic model of the new type of damper, excellent energy-consumption performance is proved in the design of metal damper in this paper.
