Data on full stationary wave-field measurement of a suspended steel plate punctually loaded.

The dataset presented contains the experimental structural response, in the frequency domain, of a suspended steel plate to a point force excitation. The plate is excited by a mechanical point force generated by a Brüel & kJær shaker with a white noise signal input from 3.125 Hz to 2000 Hz.

Experimental pseudo-equivalent deterministic excitation method extension for low frequency domain applications.

In transport engineering applications, flow-induced vibrations is an interesting topic to address since it may negatively affect the operation and the response of the system. Wind tunnel facilities are mandatory to test the structure design efficiency or to analyse new material performances under aerodynamic load. However, these experimental tests can be expensive and take a long time to set up and operate; hence, alternative methods for the reproduction of the structural response to a turbulent boundary layer excitation are required to accelerate and improve the experimental setups and provide more data for uncertainty analysis.

Pseudo-equivalent deterministic excitation method application for experimental reproduction of a structural response to a turbulent boundary layer excitation.

In the transportation engineering field, the turbulent boundary layer over a structure is one of the most relevant sources of structural vibration and emitted noise. Wind tunnels are still one of the best options for vibroacoustic experimental analyses for this specific problem. However, it is also true that this experimental method is not always affordable, due to several limitations-settings hard to control, time and money consumption, discrepancies among laboratories-that wind tunnel facilities present.

Data on full wave-field measurement of transient guided resonance pulses propagating in a composite structure.

Guided resonances (GR) are high-order, unidirectional waves able to propagate over a long range in finite cross-sections' waveguides. Near cut-on GR exhibit a variety of scattering behaviors going from zero group velocity to quasi non-dispersive propagation. This data article presents the surface velocities measured during the propagation of near cut-on high-order guided resonances in a 3-m-long sandwich panel.

Improving sound transmission loss at ring frequency of a curved panel using tunable 3D-printed small-scale resonators.

An important dip in the sound transmission loss of curved panels occurs at the ring frequency. The relevance of using small-scale resonators to solve this issue is experimentally demonstrated on an aircraft sidewall panel. The effect of varying the spatial distribution of single frequency resonators (including combination with a broadband soundproofing treatment), as well as using multi-frequency resonators with a fixed spatial distribution is studied.
