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.
