摘要
应用 ANSYS 软件对半球谐振陀螺仪谐振子的振动特性进行了有限元分析,建立了Ψ型半球壳谐振子的有限元模型,计算出了谐振子的固有频率及振型。在理论分析的基础之上,提出了对于Ψ型半球壳谐振子的结构设计的合理建议。
The vibrating characteristics are analyzed on the resonator of hemispherical resonator gyro with the software ANSYS. The finite element model of the Ψ-shaped hemispherical shell resonator is established. The natural frequency and the mode of the above resonator are calculated. On the basis of the analyses of vibration features of the resonator, the proper suggestions for engineer design of the Ψ-shaped hemispherical shell resonator are made in this paper.
