Dimensional considerations in the evaluation and design of energy dissipaters

This paper presents an experimental and simulation-based investigation into the force characteristics of rubber ball-based energy dissipaters. The study focuses on exploring the dimensional considerations in energy dissipation, where rubber balls serve as a medium to control vibrations. The paper scrutinizes the force properties through various approaches, including filling ratio, rotor speed, dissipater dimensions, and ball size. The results indicate that the size of the rubber balls significantly improves the performance of the energy dissipater, suggesting that larger balls enhance their effectiveness. Additionally, enhancing the filling ratio and the dimensions of the energy dissipater results in greater force. A numerical simulation technique based on the discrete element analysis method is employed to supplement the experimental findings for an exhaustive quantitative and qualitative analysis of the energy dissipater. The close correlation between the experimental and simulation results confirms the accuracy of the proposed model, especially for large-scale energy dissipation systems.
