The Analysis of Vibroviscosity Sensor Functionality in the Mode of Tuning the Frequency of the Forced Oscillations 000_14.pdf

The analysis of the vibroviscosity sensor work in the proposed mode of forced oscillations with maintaining the specified value of the phase difference between the excitation signal and the response signal by tuning the frequency of the excitation signal is carried out. The method for calculating the current value of the Q-factor and the natural frequency with the use of the results of measuring the amplitude of forced oscillations and the phase difference between the excitation and output signals of the oscillatory system is considered. The author made the analysis of the system performance in the mode with discrete frequency tuning and error estimation of the oscillatory system parameters with the generator frequency that is not equal to the natural frequency of the oscillatory system. Some recommendations concerning the rational choice of the step changes of the output generator signal frequency are provided.
