Dataset of experimental measurements for the Orion beam structure.

ABSTRACT: This data article comprises experimental data to investigate the nonlinear dynamic behavior of the Orion beam structure, which consists of two duraluminum beams assembled by bolted joints. To retain contact on a small area between both beams, this new lap-joint configuration proposes contact patches at each bolt connection. The Orion beam suggests an assembly configuration that associates bolts dedicated to 'static' functions and to those to perform 'damping' functions. This ensures a significant increase in the structural damping without degrading the structural stiffness. Experiments have been performed on the laboratory ple Vibration and Acoustic, located at FEMTO-ST Institute, CNRS/UFC/ENSMM/UTBM, Department of Applied Mechanics, 24 chemin de lEpitaphe, 25000 Besanon, France. This data aim to provide the geometrical step and all the experimental measurements performed on our lap-joint for several excitation amplitudes and tightening torques, as far as possible and with the degree of uncertainties of the measurements. By doing so, we intend to provide experimental data, as precise and reliable as possible, which are required to progress on the numerical modelling of the dry friction damping in assembly structures. This Data in Brief article is an additional research item alongside the following paper published in the Mechanical Systems and Signal Processing journal: R. O. Teloli, P. Butaud, G. Chevallier and S. da Silva, Good practices for designing and experimental testing of dynamically excited jointed structures: the Orion beam.

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

Project description: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.

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

Project description: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.

Experimental dataset for measurements of freely vibrating structures equipped with impact dampers.

Project description:This data article comprises the experimental data during testing a vibration control technique for structural and mechanical systems which uses new passive vibrational control device called the linear particle chain impact damper (LPCID). The LPCID consists of freely moving spherical balls of different sizes arranged linearly inside a rigid container. The data were collected by taking precise measurements from a custom-designed experimental setup. The data were collected for a freely vibrating frame structure which was released from an initial position by an electromagnet. The data presented in the article will provide a path for researchers to validate the dynamic models for several types of impact dampers such as single-unit and multi-unit impact dampers. The data will also help in understanding the nonlinear behaviour of this type of impact dampers. The article also comprises data for examining the performance of the LPCID by varying the design parameters, including mass ratios, damper clearance and chain length. The article is related to research articles by Gharib and Karkoub (2017) [1].

Experimental demonstration of novel beam characterization using a polarizable X-band transverse deflection structure.

Project description:The PolariX TDS (Polarizable X-Band Transverse Deflection Structure) is an innovative TDS-design operating in the X-band frequency-range. The design gives full control of the streaking plane, which can be tuned in order to characterize the projections of the beam distribution onto arbitrary transverse axes. This novel feature opens up new opportunities for detailed characterization of the electron beam. In this paper we present first measurements of the Polarix TDS at the FLASHForward beamline at DESY, including three-dimensional reconstruction of the charge-density distribution of the bunch and slice emittance measurements in both transverse directions. The experimental results open the path toward novel and more extensive beam characterization in the direction of multi-dimensional-beam-phase-space reconstruction.

A vibrating beam MEMS accelerometer for gravity and seismic measurements.

Project description:This paper introduces a differential vibrating beam MEMS accelerometer demonstrating excellent long-term stability for applications in gravimetry and seismology. The MEMS gravimeter module demonstrates an output Allan deviation of 9 ?Gal for a 1000?s integration time, a noise floor of 100 ?Gal/?Hz, and measurement over the full ±1?g dynamic range (1?g?=?9.81?ms-2). The sensitivity of the device is demonstrated through the tracking of Earth tides and recording of ground motion corresponding to a number of teleseismic events over several months. These results demonstrate that vibrating beam MEMS accelerometers can be employed for measurements requiring high levels of stability and resolution with wider implications for precision measurement employing other resonant-output MEMS devices such as gyroscopes and magnetometers.

Accuracy of linear measurements obtained from stitched cone beam computed tomography images versus direct skull measurements.

Project description:Background: To assess whether the linear measurements obtained from stitched cone beam computed tomography (CBCT) images were as accurate as the direct skull measurements. Methods: Nine dry human skulls were marked with gutta-percha at reference points to obtain Twenty-two linear measurements on each skull. Ten measurements in the cranio-caudal plane, two measurements in the antero-posterior plane, and ten measurements in the medio-lateral plane. CBCT linear measurements obtained using stitching software were measured and compared with direct skull measurements. Results: The absolute Dahlberg error between direct linear measurements and linear measurements on stitched CBCT images ranged from (0.07 mm to 0.41 mm). The relative Dahlberg error ranged from (0.2% to 1.8%). Moreover, Intra-class Correlation Coefficient (ICC) ranged from (0.97 to 1.0) indicating excellent agreement. Conclusion: Stitched CBCT linear measurements were highly comparable to the direct skull measurements using a digital caliper.

Fiber-tip polymer clamped-beam probe for high-sensitivity nanoforce measurements.

Project description:Micromanipulation and biological, material science, and medical applications often require to control or measure the forces asserted on small objects. Here, we demonstrate for the first time the microprinting of a novel fiber-tip-polymer clamped-beam probe micro-force sensor for the examination of biological samples. The proposed sensor consists of two bases, a clamped beam, and a force-sensing probe, which were developed using a femtosecond-laser-induced two-photon polymerization (TPP) technique. Based on the finite element method (FEM), the static performance of the structure was simulated to provide the basis for the structural design. A miniature all-fiber micro-force sensor of this type exhibited an ultrahigh force sensitivity of 1.51 nm μN-1, a detection limit of 54.9 nN, and an unambiguous sensor measurement range of ~2.9 mN. The Young's modulus of polydimethylsiloxane, a butterfly feeler, and human hair were successfully measured with the proposed sensor. To the best of our knowledge, this fiber sensor has the smallest force-detection limit in direct contact mode reported to date, comparable to that of an atomic force microscope (AFM). This approach opens new avenues towards the realization of small-footprint AFMs that could be easily adapted for use in outside specialized laboratories. As such, we believe that this device will be beneficial for high-precision biomedical and material science examination, and the proposed fabrication method provides a new route for the next generation of research on complex fiber-integrated polymer devices.
