摘要
设计了一种简单可靠的调谐质量阻尼器(TMD)模拟装置,并首次开展了TMD抑制拉索振动的参数试验研究。建立了拉索与单个TMD耦合振动的理论分析模型,并运用复模态方法讨论了拉索-TMD系统的耦合振动特性。理论研究与试验结果的对比分析证明了所设计TMD模拟装置的有效性,利用TMD抑制超长拉索振动是可行的。
A theoretical method to coupled vibration of cable-TMD system is proposed, and complex modal method is used to derive the coupled vibration characteristics of cable-TMD system in the paper. Experimental model of cable-TMD system is designed, and the theoretical analysis results for coupled vibration of cable-TMD is verified by the experimental results. This research conclusion can provide the technical support for the using of TMD in mitigating super long cable vibration.
