Vibrating Plates (Vibrating Plates Dataset for Vibroacoustic Frequency Response Prediction)

We present a structured benchmark dataset for a representative vibroacoustic problem: Predicting the frequency response for vibrating plates. The vibrating plates benchmark dataset consists of in total 12,000 varied plate designs and accompanying vibration patterns, when the plates are excited by a harmonic force. These vibration platterns give the vibration velocity at every location of the plate orthogonal to its surface. The plate designs incorporate randomly placed beadings, indentations in the plate surface. The beadings stiffen the plates and completely change the resulting vibration patterns. Additionally, the size, thickness and damping loss factor of the plates are varied.

The dataset is intended to further the development of surrogate modeling methods for partial differential equations in the field of vibroacoustics. It contains two settings, G-5000 and V-5000. Both incorporate the beading pattern variation but only G-5000 additionally includes the variation of plate size, thickness and damping loss factor.
