摘要: In the present study, piezoelectric resonators under lateral field excitation (LFE) based on a LiTaO3 single crystal are modeled and analyzed. An electrically forced vibration study is employed to acquire motional capacitance curve mode shapes. A finite element approach utilized investigate influences of some basic parameters, such as electrode/plate mass ratio, electrode gap, width resonance characteristics. addition, design criteria for gap LFE obtained by analyzing effects those parameters strain distributions. The results essential designing using crystal.
