Figure 3 displays the frequency response curve of the DRG. The radial displacement 𝑑1 of the node is indicated by a red circle at the top of an inset drawing of the DRG. The radial displacement 𝑑1 is representative of the drive mode. The frequency response (𝑑1, in microns) is plotted against the frequency response between a range of 32.62 kHZ and 32.65 kHZ. The prediction step of the DL-ROM was performed in less than 1s using a Tesla V100 32GB GPU implemented in a TensorFlow DL framework.
