Abstract

Platform frame structure is the key part of Inertial Navigation System. In order to design and improve the dynamic characteristic of structure, the method of finite element analysis and three-dimensional modeling is used to analysis and calculation the modal and sensitive of the platform structure. To provide some references for the optimization of structure and determining the optimal structure, this calculation proved that the structure has better dynamic characteristics after improvement. Finally, the design and mounted position of vibration damper is analyzed and calculated, and then analyze the effects of the vibration damper. This research would be a guidance for the same type design in the future.
