TMD现场调试是保证TMD减振效率的重要手段。准确识别安装TMD后的结构-TMD耦合系统的结构模态参数和TMD 物理参数是TMD现场调试的必需条件，然而，现有的参数识别方法只能识别耦合系统的模态参数，无法通过耦合系统的动力响应识别被控结构模态参数和TMD物理参数。为了实现TMD现场调试，本项目将开展结构-TMD耦合系统的被控结构模态参数和TMD物理参数识别理论与试验研究。该方法首先利用识别的耦合系统模态参数和模型减缩技术构造单模态结构和TMD耦合的状态空间模型；然后，利用该状态空间模型识别结构模态参数和TMD物理参数。研究成果将建立一套完整的结构-TMD耦合系统的结构模态参数和TMD物理参数识别技术，为TMD现场调试提供全面、准确的参数，保障TMD的减振效率，具有广阔的应用前景。

Field adjustment of TMD is an effective measurement to ensure the efficiency of TMD. Accurate identification of the structural modal parameters and TMD physical parameters for structure-TMD coupled system after the installation of TMD is necessary to field adjust TMD. However, traditional parameter identification method identifies the modal parameters of the structure-TMD coupled system rather than the structural modal parameters and TMD physical parameters. To realize field adjustment of TMD, in this program, a new method has been studied to identify structural modal parameters and TMD physical parameters of the structure-TMD coupled system. Firstly, the state space model of single modal structure and TMD coupled system is estimated by using the estimated modal parameters of the real structure and TMD coupled system and model reduction technique. Then, the estimated state space model is used to identify structural modal parameters and TMD physical parameters. Based on detailed studies, a technique to identify structural modal parameters and TMD physical parameters of the structure-TMD coupled system is developed. It is of great significance for this technique to promote the application of TMD and improve the control efficiency of TMD.
