| 摘 要： | 总结了传统调谐质量阻尼器(TMD)在涡激振动控制中的工作性能，提出运用多重调谐质量阻尼器(MTMD)理论进行TMD设计，提高振动控制的鲁棒性；开发了电涡流阻尼器取代传统油阻尼器作为TMD的阻尼发生装置，延长TMD的疲劳寿命.利用遗传算法实现了MTMD的参数优化设计，与TMD的比较表明，MTMD在控制效率和鲁棒性方面具有更优越的综合性能.电涡流TMD在试验和实际工程中的成功应用表明电涡流TMD在桥梁振动控制领域具有广阔的应用前景.

| Abstract: | The performances of traditional tuned mass damper (TMD) intended for suppressing the vortex-induced oscillation of bridges were invesitgated. In order to improve the robustness of traditional TMD, multiple tuned mass dampers (MTMD) theory was proposed to design TMDs. Furthermore, a new damper, namely the eddy current damper, was developed to repalce traditional oil damper as the damping producer of TMD, so the fatigue life-span of TMD was greatly extended. The parameter design of MTMD was realized by making use of genetic algorithm. And the results of comparison between TMD and MTMD have indicated that MTMD is superior to TMD, when their effectiveness and robustness are of equivalent importance in design. Both experiments and engineering practice of eddy current TMD were successfully conducted, showing a promising future of eddy current TMD in the field of bridge vibration control. |
