Modal Analysis of Dynamically Tuned Gyroscope Based on ANSYS11.0

This paper proposed a method to analyses and obtain the vibration identities of DTG(Dynamically Tuned Gyroscope) within the vibration-overloading environment based on ANSYS11.0. Finite element model of DTG was constructed by ANSYS11.0. The Natural Frequencies and vibration modals of DTG in the cases of both being stationary and rotating were studied respectively through the method of modal analysis. The influence of each-rank vibration model of DTG on its output was investigated. The result of this paper provides a stable basis for improving the design of DTG and enhancing the functions of it.
