Abstract

An accelerometer is a transducer that, on its own or in conjunction with electronics, instantly transmits an electrical signal corresponding to the force applied to its base. To measure vibrations with a capacitive accelerometer, it is important to know its accuracy, exact sensitivity, and reliability but sometimes the phase of the signal or the frequencies of interest. This paper chooses the capacitive accelerometer through its advantages over other types. The modeling of this type of accelerometer has been the subject of extracting from new formulas linked to the characteristics of the capacitive sensor and the simulation of the developed models makes it possible to minimize the measurement error, maximize the measurement accuracy, and reduce the electrical energy consumption by the appropriate choice of the damping rate and the frequency margin. A new equation for damping rate according to error is extracted by using the developed model. This equation makes easier the choice of damping rate that will minimize error to a very low value and maximize accuracy. This developed model is confirmed by experimental tests and finally, a new design of the capacitive accelerometer is proposed.
