Dataset collected using a control strategy on a triaxial platform

This dataset presents experimental results from a multiaxial vibration test campaign conducted on a triaxial electrodynamic shaker platform. The aim was to assess how different acceleration-control strategies influence the dynamic response of the platform and cross-axis effects. Four closed-loop strategies were investigated: (1) single-point control using one triaxial accelerometer, (2) control using three single-axis accelerometers, one per axis, (3) distributed control using three triaxial accelerometers, and (4) multi-point response with rectangular control through three accelerometers. Acceleration measurements were collected during sweep-sine and random vibration tests over the 5-2000 Hz frequency range.

All data were acquired on the LMN triaxial vibration test bench, which enables coupled or uncoupled excitation along three orthogonal axes. Signal generation, closed-loop control, and data acquisition were performed using Spectral Dynamics Jaguar hardware and software. The instrumentation consisted of five triaxial accelerometers and three single-axis accelerometers mounted on the platform. Sweep-sine tests were conducted at 1.5 g with a sweep rate of 1 octave per minute, whereas random vibration tests were performed at 1 g-RMS for 5 min. The dataset includes raw sweep-sine spectra (.frq), frequency response functions (.frf), random-vibration power spectral density files (.psd), and MATLAB post-processed figure files (.fig).
