“…Then, a total of 12 parameters (main sensitivities, transverse sensitivities and offsets) are evaluated; a linear least squares optimization is used to estimate them, as described in the references (D'Emilia et al, 2015(D'Emilia et al, , 2016a.…”

“…In this paper, new calibration techniques are investigated, with the purpose of increasing the flexibility of the traditional calibration procedures (ISO 16063-1, 1998;ISO 16063-11, 1999;ISO 16063-31, 2009), to tailor them to the variable conditions and requirements of the field while guaranteeing, at the same time, traceability and accuracy (Schiavi et al, 2015;D'Emilia et al, 2011D'Emilia et al, , 2015. An example is the pos-sibility of developing procedures that could be implemented both on-line and in-line (Frosio et al, 2009(Frosio et al, , 2012Glueck et al, 2012;Fong et al, 2008).…”

Abstract. Two alternative experimental procedures for the calibration of tri-axial accelerometers have been compared with traditional methods, performed according the procedures stated in the standard ISO 16063-21. Standard calibration is carried out by comparison with a laser Doppler vibrometer (LDV), used as a primary reference transducer. The main sensitivities have been investigated and, where applicable, also transverse ones. Many aspects have been evaluated: the hypotheses about transverse sensitivities, the simplicity of the procedure, the number of measurements needed, and the effect of typology of transducer, depending on electrical and geometrical contributions. Two different accelerometers have been tested, a piezo-electric accelerometer and a capacitive MEMS accelerometer. A low-frequency range of vibration has been investigated, 3 and 6 Hz, with amplitude of acceleration ranging from 2 to 20 ms−2. A satisfactory reproducibility of methods has been verified, with percentage differences less than 2.5 %. Anyway, pros and cons of each method are also discussed with reference to their possible use for easy and quick calibration of low-cost tri-axial accelerometers.

Abstract. A method for amplitude–phase calibration of tri-axial accelerometers in the low-frequency range (0 to 20 Hz) is proposed, based on a linear slide, used to excite all the axes of the accelerometer at the same time, and a laser Doppler vibrometer (LDV) as a reference. For the phase evaluation different methods, like cross-correlation analysis and cross-spectrum analysis, have also been used for validation purposes. The procedure includes many further validation actions in order to verify the correctness of modelling of the systems being tested, of the data processing and to reduce the calibration uncertainty. Results show that the phase is a critical aspect to consider in calibration, more than the amplitude, and the comparison with the theoretical model is useful to verify the hypotheses. Different behaviours result depending on the elements of the measurement chain and not only on the type of accelerometer.

“…Auersch [17] conducted the theoretical and experimental analysis on the attenuation law of the surface wave with distance and discovered that the amplitude attenuated with the distance follows a power function. Different acceleration sensors and installation methods may obtain different vibration value in the field vibration tests [18]. In addition, the vibration characteristics of different foundations are different greatly, and Senetakis [19] compared the vibration characteristics of the cinerite and quartz sand via the resonant-column experiments.…”

When a high-power vibrating roller compact the subgrade, the vibration wave will quickly propagate along the surface of the subgrade and generate hazards to surrounding environment and structure. To study the vibration propagation rules of the roller, the vibration acceleration of the high-power vibrating roller was measured on the surface of the rock subgrade, coarse-grained soil subgrade and fine-grained soil subgrade. The respective relations between vibration acceleration and the distance from a vibration source in the vertical, horizontal radial and horizontal circumferential direction have been discovered. The research results show that the vibration peak frequency generated by the vibrating roller on the subgrade approximates vibration frequency. The vibration effective influence distance varies from 10m to14m, and the horizontal radial vibration is greater than that of vertical and horizontal circumferential direction. The vibration of the rock subgrade attenuates the most slowly and propagates the most remotely.
