  • Abstract The structure of hybrid TMD and TLD damping frequency and LPMSG applications in two degrees of freedom in this study. The use of different water depths and tuned mass damper weight change to explore the best damping range. Hybrid TMD and TLD system, when the external forcing frequency of the Dynamic Vibration Absorber System composed by a tuned liquid damper and a tuned mass damper is identical to the fundamental frequency of the tank, the external force can be effectively diminished by the sloshing-induced force. Under the Hybrid TMD and TLD system, the energy will concentrated in LPMSG at the Eigen frequency. The reason is the shaking of TMD will decrease the coupling force between TLD and base structure. This can highly decrease the shaking displacement of the base structure. On the other hand, the shaking displacement and the velocity of LPMSG will increased to maximum. Therefore, the generating power will increased.
