Originální abstrakt

This paper deals with finite element simulations of impedance characteristics piezoelectic elements utilized in sensors of acoustic emission (AE). Coefficients of piezoelectric material are changed to evaluate the sensitivity to their variation in case they are not known precisely, so to which extent can they influence the sensitivity of the sensor. Result showed sensitivity on coefficient in c-matrix, mainly to coefficients c11 and c13. Second investigated topic is issue with test stand for calibration of AE sensors, where output of force sensor was affected by parasite signal. By contactless measurement with laser interferometer was discovered the parasite signal is caused by mechanic of the system and it is no threat for the measuring chain.
