Impact testing of an arch model using tuned mass dampers with initial displacement

We propose TMDs (Tuned mass dampers) with initial displacement that are possible to control initial transient responses effectively. In our previous study, we proposed the optimal design formulas of TMDs with initial displacement to control impulse responses focusing on modal damping ratios of two vibration modes and formulated the initial conditions of TMD displacement release. In this paper, we describe the vibration test using an arch model under impulse loading to verify the control performance of the proposed method experimentally. Then, we study the influence of different conditions about the length and the release time of TMD initial displacement on the control performance analytically.
