This paper presents an analytical method to determine optimal parameters of tuned mass damper (TMD), such as the ratio between natural frequency of TMD and shaft, the ratio of the viscous coefficient of the TMD. Two novel findings of the present study are summarized as follows. First, the optimal parameters of the TMD for the shafts are given by using the fixed-point theory (FPT). Next, a numerical simulation is done for an example of the machine shaft to validate the effectiveness of the results obtained in this study. The simulation results indicate that the proposed method significantly increases the effectiveness in torsional vibration reduction of the machine shaft. | Determining optimal parameters of the tuned mass damper to reduce the torsional vibration of the machine shaft by using the fixed-point theory
