摘要
本文提出了一种新型舌板黏滞阻尼器,通过对该黏滞阻尼器进行低周循环加载试验和抗低周疲劳性能试验,研究并验证了该阻尼器的耗能性能、抗低周疲劳性能及恢复力模型。研究结果表明:选取合适参数的舌板式黏滞阻尼器滞回曲线饱满,耗能性能与抗低周疲劳性能良好。Maxwell模型能够较好地描述该阻尼器力学行为,反映阻尼器在各种试验工况下的出力情况。该阻尼器设计与加工简单,对工程结构的耗能减震有着实际意义。
A new viscous damper with tongue plates(TPVD)was proposed in this paper. Low-cycle reversed loading and fatigue performance tests were conducted on the specimens to validate their energy dissipation performances. Low-cycle fatigue resistance and restoring force model were studied as well. The results show that the TPVD with appropriate damper parameters have good energy dissipation performance and low-cycle fatigue resistance. Based on the hysteresis curves,the Maxwell model was found to be able to accurately describe the behavior of the damper and reflect the output of the damper under various test conditions. The damper is simple in design and manufacture,which has practical potential for energy dissipation and vibration reduction for engineering structures.
