Design and Analysis for Platform Component of Strapdown Inertial Measurement Unit

Platform component is the key part of strapdown inertial measurement unit. Based on the technological need of a new type of strapdown inertial measurement unit, three dimensional modeling and Finite Element Analysis (FEA) is used to design the platform component structure. And then, the optimal structure of platform component is determined on the basis of analysis and calculation. The calculation proved the platform has better intensity and dynamic characteristic. At last the design parameter and structural style and mounted position of vibration damper is analyzed particularly. This study would be a guidance for the design of new type of strapdown inertial measurement unit in the future.
