摘要
针对钟形振子式角速率陀螺(Bell-shaped vibratory angular rate gyro)振子的振型特性进行仿真研究,提出一种金属壳谐振陀螺的振型特性分析方法,并给出求解过程与仿真分析结果。在Kirchhoff-Love假设的前提下,通过数值解析方法,求解出钟形振子的振型函数,找到钟形振子基本低阶振型的分布规律;通过与有限元仿真结果进行综合分析,对钟形振子振型特性进行总体评估,有效的分析了钟形振子的振型特性。通过理论推导与仿真分析相结合的方式,验证了理论推动振型函数的正确性,为钟形振子式角速率陀螺的研制奠定理论基础。
It presents the analysis method of metal shell vibratory gyro＇s mode shape for simulation research on Bell-shaped vibratory angular rate gyro, and gives the solution process and result of simulation analysis. Based on the Kirchhoff-Love assuming, by numerical methods to solve mode shape functions of bell-shaped resonator, the low-order modes of bell-shaped resonator is given through comprehensive analysis and finite element simulation results. The mode shaped characteristics of bell-shaped resonator is analyzed effectively through this method. Theory and simulation methods verify the correctness of the theory and promote modal, and lay the bell-shaped vibratory angular rate gyro development of theoretical basis.
