Electromechanical Coupling Characteristics Analysis of Bell-Shaped Vibratory Angular Rate Gyro
摘要
Abstract
Bell-shaped resonator as the core of the bell-shaped vibratory angular rate gyro(BVG),which will directly affect the electromechanical coupling characteristics of BVG's overall performance.For BVG in design making process in the not involved of electromechanical coupled characteristics expand analysis,proposed using elastic mechanical in the of energy principle and Lagrange method established bell-shaped resonator coupled model of method,solution has bell-shaped resonator drive and detection between of multi-field built problem,achieved has bell-shaped resonator of electromechanical coupled relationship of linear characterization.Firstly,it detected through the analysis of piezoelectric-driven principles by coordinate transformation given piezoelectric potential of the electrode in the bell-shaped resonator function can be stated using elastic energy in principle and Lagrange method of electromechanical coupling model of bell-shaped resonator,analysis of relationship between electrode and bell-shaped resonator,bell-shaped resonator electrodes piezoelectric parameters were determined.Through a means test to verify results and availability.关键词
