Opis:: Ways of adjusting MEMS accelerometers for tilt measurements over a small angular range of few degrees arc or less are considered with regard to achieving a possibly high accuracy. The paper describes some additional mechanical structures applied to overcome the problem of incompatibility between the large measuring range of MEMS accelerometers and the expected small angular measuring range.

Tytuł:: Accelerometer - Based Measurements of Axial Tilt
Autorzy:: Łuczak, S.
Powiązania:: https://bibliotekanauki.pl/articles/384680.pdf
Data publikacji:: 2012

Tematy:: MEMS

Opis:: The paper deals with a specific type of tilt measurements, where an axial tilt is to be determined. The measurements are realized by means of accelerometers - MEMS devices most preferably. Various mathematical relations between the axial tilt and the Cartesian components of the gravitational acceleration are presented. Each relation is described in detail, especially in the terms of the resultant uncertainty of the measurement, as well as the requirements regarding the employed accelerometers. Results of experimental studies realized by means of commercial MEMS accelerometers are presented and discussed, especially with regard to the measurement accuracy that has been evaluated for each mathematical relation. Scope of application of each relation is proposed.

Opis:: W artykule przedstawiono problem doświadczalnego wyznaczania wartości najważniejszych parametrów metrologicznych akcelerometrów MEMS (Microelektromechanical Systems). Zaprezentowano odpowiednie stanowisko badawcze. Omówiono różne metody wzorcowania akcelerometrów.

In the cases when metrological parameters of a sensor are of high importance, it is necessary to subject it to appropriate experimental studies. Generally, such a situation may take place when: significant metrological parameters of a sensor are not provided or may be overestimated in the related catalogs; a sensor must be calibrated by the user; an improvement of the sensor performance is striven for; significance of interactions between a sensor parameter and some disturbance must be verified; results of aging of a sensor, its durability or stability must be determined. Such cases are reported in [1-4]. While performing experiments described in the paper, two crucial issues were: an appropriate test rig presented in Section 2, and a methodology of performing the experiments discussed in the paper and in [8]. In Section 3 various ways of calibrating MEMS accelerometers are presented, with reference to related works of others, reported in [11-14], and their advantages and disadvantages are briefly discussed. Two original procedures of calibration are proposed. In the summary, the results obtained while calibrating the tested accelerometer according to three different methods are compared, and then a scope of application of each method is indicated. Further results of the considered experiments are reported by the author in the paper constituting a second part of the presented considerations, 'Experimental determination of selected parameters of MEMS accelerometers - results of the experimental studies'.

Tytuł:: Dual-axis test rig for Mems tilt sensors

Opis:: The paper addresses the problem of experimental studies of miniature tilt sensors based on low-range accelerometers belonging to Microelectromechanical Systems (MEMS). A custom computer controlled test rig is proposed, whose kinematics allows an arbitrary tilt angle to be applied (i.e. its two components: pitch and roll over the full angular range). The related geometrical relationships are presented along with the respective uncertainties resulting from their application. Metrological features of the test rig are carefully evaluated and briefly discussed. Accuracy of the test rig is expressed in terms of the respective uncertainties, as recommended by ISO; its scope of application as well as the related limitations are indicated. Even though the test rig is mostly composed of standard devices, like rotation stages and incremental angle encoder, its performance can be compared with specialized certified machines that are very expensive. Exemplary results of experimental studies of MEMS accelerometers realized by means of the test rig are presented and briefly discussed. Few ways of improving performance of the test rig are proposed.

Opis:: W artykule przedstawiono problem doświadczalnego wyznaczania najważniejszych parametrów metrologicznych akcelerometrów MEMS. Szczegółowo omówiono zagadnienie justowania akcelerometrów względem stanowiska badawczego. Wskazano na niewyjustowanie akcelerometru jako najistotniejsze źródło błędów wskazań tych przyrządów. Podano wartości niektórych parametrów metrologicznych dla przykładowych akcelerometrów. Odniesiono się do podobnych prac prowadzonych przez różne ośrodki badawcze na świecie.
paper addresses the issue of determining metrological parameters of MEMS accelerometers in an experimental way. Methodology of performing such studies as well as the related test rig are presented by the author in [1]. Short discussion on similar works carried out by others, reported e.g. in [2-4], [8-10], [14-15], is included. Much attention is paid to the problem of aligning the accelerometer in the test rig. The obtained results proved that misalignment is a factor affecting the sensor accuracy most significantly. That can be clearly observed by comparing the courses in Figs. 2 and 3, where the misalignment almost directly increased the error of sensor indications. Such errors as cross-axis (or transverse) sensitivity, perpendicularity of the sensitive axes and hysteresis are briefly addressed in Sections 4-6. Yet even though magnitudes of these errors are not significant in the case of dual-axis accelerometers that have been tested, it may turn out that it is not so in the case of triaxial accelerometers . It is shown that owing to compensation of systematic errors (such as the cross-axis sensitivity or misalignment) or even elimination of various kinds of errors (e.g. misalignment, errors resulting from the accepted way of calibration) an improvement in sensor performance may be achieved. At the end, some parameters as estimators of the accuracy of MEMS accelerometers are proposed.
