This thesis explores the effectiveness of an impact damper, which represents an alternative method for introducing damping into a dynamic system. First, the primary structure and the impact damper were designed and fabricated, followed by setting up the experiment on an electrodynamic shaker. We examined the influence of mass ratio on the damping ratio under sinusoidal excitation and the effects of mass ratio and various cavity wall materials on the damping ratio at different levels of excitation with random signals. Results from sinusoidal excitation indicate that a higher mass ratio increases the damping ratio, while results from random excitation underscore the significance of cavity wall material selection.
