Design and Dynamic Characteristics Study on structure of MIMU Damping System
Proceedings of the 2015 3rd International Conference on Machinery, Materials and Information Technology ApplicationsAdvances in Computer Science Research（2015）
Abstract
The accuracy of a micro inertial navigation system is greatly influenced by the complex vibration environment of the vehicle, an embedded vibration attenuation system structure is designedand its rigidity is checked. The correctness of this structure design is verified through the modal analysis and frequency response analysis using the finite element analysis software. Finally, based on the frequency response analysis, the model of damping system is carried out the random vibration response analysis, and an acceleration power spectral densitycurve of the structure under the vibration environment is obtained, which provides a reliable basis for the structure design.
