Sidorenko O.M., Salanov A.A., Kozlov A.I.  Mathematical modeling of sensitive element of angular velocity sensor using ANSYS CAE software

The paper presents the results of mathematical modeling of a sensitive element of a Coriolis vibratory gyroscope. The modeling was done by finite element method using ANSYS CAE software. The gyroscope’s sensitive element has the shape of a double tuning fork. The amplitude-frequency response and signal parameters are obtained, which ensure the sensitive element operation in force-to-rebalance mode. The simulation results are compared with the experimental ones.

Fedosov I.I.  A method for estimating the measurement status of a four-electrode thermoelectric transducer’s measuring circuit

Industrial temperature measurements are typically based on contact transducers, such as thermistors and thermocouples. The latter enable measurements in a wide temperature range and with high precision, but their application in industrial environments results in the degradation of thermoelectric material properties and the growing temperature measurement error. The paper offers a method for estimating the result of temperature measurement on the basis of a four-electrode measuring circuit of a thermoelectric transducer. The method makes it possible to obtain measurement result status as valid, indicative, and invalid for each measurement in the operating temperature range. Experimental investigation of the method for a four-electrode chromel-alumel-nichrosil-nisil transducer has confirmed the possibility of evaluating the increase of transducer’s measurement error at the level of admissible deviations.
