バーベル型振動部を有する新形状縦水晶振動子の振動解析

抄録

An object of this paper is to propose a new shape length extensional mode quartz crystal resonator with barbell type vibration bar and to clarify its resonant frequency, frequency temperature behavior and electrical characteristics, taking account of lateral motions. In analysis procedure, equation of motion for the new shape resonator consisting of a vibrational portion and two supporting portions is derived from an energy method. From the obtained equation of motion, a frequency equation is calculated. Frequency characteristics, frequency temperature behavior and electrical characteristics are analyzed. These results are then compared with the measured data.
