摘　　要：在动力吸振及优化的频率比、阻尼比研究的基础上,设计了调谐质量阻尼器,并基于实体模型开展了振动控制研究,其模态计算频率与设计频率一致。随之,开展了建筑楼盖调谐质量阻尼器振动控制研究,与调谐质量阻尼器质点模型对比研究结果肯定了实体模型设计及计算分析的准确性。继而在此基础上,在有限元环境设计了一种基于实体模型的主动型调谐质量阻尼器,振动控制分析结果及作动器出力肯定了所提方法的有效性。本研究对调谐质量阻尼器在工程应用层面具有指导意义,对主动、半主动等先进型调谐质量阻尼器开发提供了有效途径,具有一定的创新性。Based on the study of frequency and damping ratio optimization for dynamic vibration absorp-tion, a tuned mass damper (TMD) was designed and vibration control research was conducted based on a solid model of TMD, and the modal result indicated that the calculation frequency was consistent with the design frequency. Subsequently, research on vibration control of building floor using TMD was carried out, and the results of the comparative study with the TMD using the mass point model which confirmed the accuracy of the design of the solid model and the computational analysis. On this basis, an active tuned mass damper (ATMD) based on a solid model was designed in the finite element environment. The vibration control analysis results and output force of the actuator confirmed the effectiveness of the proposed method. This study has guiding significance and a certain degree of innovation for the engineering application of TMD and provides an effective approach for the development of advanced types of TMD, such as active and semi-active types etc.
