| Abstract(in English) | The influence of a support to the double-resonant flexurally- vibrating bar was analyzed by an equivalent circuit.As a result,a design guideline for the support was obtained.The composite-type bar supported by a slender metal wire of frame type is studied here.A common nodal point does not exist to the double-rezonant modes.There is the case that these modes are coupled through the supporting-wire.A leakage output occurs by this coupling in a vibratory gyroscope.Also,a spurious response is caused by the antiresonance of support-wire.In the T-type equivalent circuit of supporting-wire,the parallel element causes a coupling between double-resonant modes,and the serial elements cause the shifts of resonant frequency.Therefore,a relation of operating frequency and dimension ratio of suporting-wire was clarified quantitatively. |
