摘　　要：研制了一种环形弹簧阻尼器(Ring spring damper,RD),通过有限元模拟研究了其力学性能。首先,给出了RD的构造并设计了一种RD试件,利用ABAQUS软件建立了其有限元模型。最后,选取不同的环形弹簧的设计参数,对RD的力学性能进行了数值分析。由研究结果可以发现,RD在往复荷载作用下具有良好的耗能及复位特性;适当增大滑动摩擦系数和外环最大厚度可有效改进RD的力学性能。In this paper,a re-centering damper with the ring spring(RD)for energy dissipation was developed and its mechanical performance was investigated.Firstly,the configuration of the RD was described and a RD specimen was designed.After that,the finite element model of the RD specimen was established by using the ABAQUS software.Finally,the numerical simulation of the RD was carried out considering different parameters of the ring spring.The results show that RD has stable energy dissipation performance and provides excellent re-centering capacity under cyclic loading.Besides,appropriate increase of the coefficient of sliding friction and the maximum thickness of the outer spring are effectively used to improve the mechanical behavior of the RD.
