Abstract:
Till now the problem of mathematical model construction for modeling resonator systems operation on the basis of piezo¬electrics remains topical. Recently there were the computer programs, allowing to carry out computations by means of a method of final elements. In the article the application of oscillation eigenmodes model for calculation of eigen-frequency spectrum of the lenticular crystal resonator of the TD-cut is considered. Calculation was made with the use of the program developed by A.N. Lepetaev. As a result of calculation quite good repeatability of A, B and C-modes frequencies calculation results has turned out, however on resistance some results have the big distinction. It is most possibly connected with influence of piezoelectric cells edges on swing. The given influence in the program is not taken into account. In the sequel it is necessary to develop the program with the presence edges influence and piezoelements points of fastening.
