Abstract

An Optimization Design Method for online tuned mass dampers (TMD) with continuous frequency conversion is presented in this article. The finite element program ANSYS-Workbench is used to study and design the structural parameters of the damper's natural frequency. A compact and lightweight structure with quick frequency conversion sensitivity is achieved using a multi-objective structural optimization approach. In addition, the simulation results show that there is a significant deviation occurs between the new resonance peak of the vibration harmonic response of the rotor system and the theoretical value. To avoid the impact of the damper mass on the new resonance peak position, the TMD is optimized topologically to achieve a lighter structure with appropriate performance. The mass of the TMD is reduced by 30%. And in the steadystate response with an optimized TMD structure, the errors between the two new peaks and the theoretical values were reduced by 38.0% and 8.1% respectively.
