Updating dataset of measurements for the experimental CEA-beam benchmark structure subjected to one stochastic broadband excitation with dataset of measurements for the CEA-beam system subjected to two correlated or uncorrelated broadband random excitations.

This data article comprises data to investigate the non-linear dynamic behavior of the beam benchmark structure that is a clamped-clamped steel beam with non-ideal boundary conditions subjected to two broadband correlated or uncorrelated random excitations. Experiments have been performed on the CEA-CESTA laboratory. The data provided include output measurements for the nonlinear dynamic behavior of the CEA-beam (i.e., the accelerations amplitudes for the three accelerometers on the beam), as well as the two input forces amplitudes. In comparison with the data provided in [4] which only considers the case of a single exitation, experimental results are extended for the CEA-beam system subjected to two correlated or uncorrelated broadband random excitations. All the results from this data will help researchers and engineers in proper analysis of the nonlinearities of the clamped-clamped beam and the effects of the correlation between two broadband correlated or uncorelated random excitations on the nonlinear signature of this academic structure. One of the main original contributions is to share the data sets to give the opportunity to researchers for testing and validating analytical or numerical models of a nonlinear beam with non-ideal boundary conditions and subjected to multipoint correlated or uncorrelated random excitations.

Dataset of measurements for the experimental CEA-beam benchmark structure subjected to one stochastic broadband excitation.

This data article comprises data to investigate the non-linear dynamic behavior of the CEA-beam benchmark structure subjected to one stochastic broadband excitation. Experiments have been performed on the CEA-CESTA laboratory. The data provided include the input Power Spectral Density for four levels of excitation and the associated output nonlinear dynamic behavior of the CEA-beam benchmark structure. All the results from this data will help researchers and engineers in proper analysis of hardening effect and the enlargement of the response peak due to one stochastic broadband excitation, as well as the presence of harmonics. One of the main original contributions is to share the data sets to give the opportunity to researchers for testing and validating analytical or numerical models of a nonlinear beam with non-ideal boundary conditions and subjected to one stochastic broadband excitation.

Dataset of multi-harmonic measurements for the experimental CEA-beam benchmark structure.

This data article comprises post-processed data to investigate the non-linear dynamic behavior of the CEA-beam benchmark structure that is a clamped-clamped steel beam with non-ideal boundary conditions. Experiments have been performed on the CEA-CESTA laboratory. The data provided include output measurements for the nonlinear dynamic behavior of the CEA-beam (i.e. the displacement amplitudes for each harmonic component at the middle of the beam), as well as the complete input acceleration signal harmonics amplitude. All the results from this data will help researchers and engineers in proper analysis of the nonlinearities of the clamped-clamped beam and the effect of the non-ideal input signal and advanced understanding of links between different excitation signal and the multi-harmonic responses of the CEA-beam. One of the main original contribution is to share the data sets to give the opportunity to researchers for testing and validating analytical or numerical models of a nonlinear beam with non-ideal boundary conditions and subjected to low and high levels of excitation signal.

Dataset of vibrational and acoustic measurements for squeal analysis from the laboratory brake setup Friction-Induced Vibration and noisE at Ecole Centrale de Lyon (FIVE@ECL).

This data article comprises raw records to investigate the dynamic behavior of a brake system during controlled braking tests and its squeal characterization through the generation of friction-induced vibration. Experiments have been performed on the laboratory brake setup Friction-Induced Vibration and noisE at Ecole Centrale de Lyon (FIVE@ECL), France. The data provided include measurements for each component of the brake system (i.e. the acceleration measurements on the two pads and the caliper and the normal displacements of the disc), as well as a complete measurement of sounds and squeal noise in near-field and in far-field during a braking test. Data of the four operational parameters (i.e. the application pressure during braking, the rotating speed of the disc, the motor torque and the temperature close to the pad/disc brake system) are also captured during experiment. All the results from this data will help researchers and engineers in proper analysis of brake squeal and advanced understanding of links between friction-induced vibration and squeal noise. One of the main original contribution is also to share the data sets to give the opportunity to researchers for testing and validating numerical models of brake system with the proposed data of squeal noise.
