Determination of bulk density of the source of heat in the analysis of thermodynamic processes in the quartz piezoelectric element

Features of bulk density determination for a heat source are considered in the analysis of thermodynamic processes occurring in a quartz piezoelectric element. Standard dependences of distribution of mechanical oscillation of piezoresonators of turning Y-cuts are shown. The paper shows the dependence of distribution of a temperature field in AT-cut piezoelectric element of the quartz resonator under conditions of variations of its excitation power.
