Dynamic Characteristic Analysis of Inertial Navigation Platform' Structure

Article Preview

Abstract:

The three-dimensional solid model and finite element model of an inertial navigation platform, is established by using ANSYS software. A modal analysis has been carried out. The former 6 ordered nature frequency and modal shape have been obtained and kept away from the frequency of Laser Gyro. The finite element model of the system vibration is established and is analysed for harmonic response. The calculation data show that vibration amplitude is very small and has no influence for the Laser Gyro working. The theory modal data is the same as the modal test results, so it manifests the accuracy and effectiveness in the modeling and analysis.
