(a) The schematic of the experimental setup. The red dot at the lower right corner is the location of excitation, while that on the upper left corner is the location where the response displacement is measured. (b) The real part (red curve) and the imaginary part (green curve) of the experimental dynamic mass of a typical DMR damper. The insert is a photo of a DMR damper. (c) The normalized experimental time trace of the displacement of the steel plate with the four DMR dampers attached after a single impulse excitation. The insert depicts the experimental response function. (d) The delayed Fourier transform spectra at different delay time obtained from the time trace in (c). The insert is the time dependent peak amplitude (red disks) obtained from the spectra and the exponent fitting (the green line).
