Application develop of finite element method in piezoelectric vibratory gyroscope

总结了目前压电振动陀螺仪的主要结构类型,重点介绍了当前研究振动陀螺仪的主要方法——有限元法。在振动陀螺仪的研究中,对于非线性应力-应变和复杂边界条件问题的处理如果采用有限元法,则更有利于问题的解决。最后总结了有限元法在研究压电振动陀螺仪系统时的材料选择、结构优化、工作特性和影响因素方面的应用。

The current main structure types and research methods of piezoelectric vibratory gyroscope are summarized. The finite element method（FEM） is mainly introduced, that is applied most widely in the research of piezoelectric devices. In the study of vibratory gyroscope, as for problems of nonlinear stress-strain and complex boundary conditions, if FEM is applied, the problems will be easily resolved. Eventually, the applications in the study of vibratory gyroscope of FEM in materials selection, structure optimization, operating characteristic and influence factor are summarized.
