环形弹簧是一种在机械工程领域中应用广泛的减振部件.将环形弹簧用于土木工程结构的减震控制，设计了一种具有自复位功能的环形弹簧阻尼器（Ring spring damper，RD），通过往复荷载作用下的性能试验，研究了RD的滞回性能.首先，提出RD的构造设计和工作原理.进而，设计加工了RD试件，对其进行了滞回性能试验，研究了位移幅值、加载频率对RD试件滞回特性的影响规律.最后，利用ABAQUS软件，对RD试件的滞回性能进行了数值模拟.研究结果表明，RD在往复荷载作用下的滞回性能稳定，且具有良好的耗能与复位特性；RD的有限元模拟滞回曲线与试验曲线较为接近，表明所建立的有限元模型可较为准确地描述该阻尼器的滞回行为.
Ring spring is a kind of vibration reduction component that is widely used in mechanical engineering field. In this investigation， the ring spring was introduced to seismic control of civil engineering structures， and a re-centering damper with the ring spring （Ring spring damper， RD） was designed. A set of cyclic loading test was conducted to investigate hysteretic behavior of the RD. Firstly， the configuration and working principle of the RD was described. Furthermore， the RD specimen was designed and fabricated. The influence of displacement amplitude and loading frequency on the hysteretic performance of the RD was studied. Finally， based on ABAQUS software， the hysteresis behavior of the RD specimen was simulated. The results show that the RD has a stable hysteretic performance and provides good energy dissipation and excellent re-centering capacity. Besides， the simulated results closely match the experimental data， indicating the validity of the established finite element model of the RD.
