Modal Analysis of Airborne Equipment Mounting Rack

摘要

Stability and safety performance of aircraft is determined by reliability of aviation airborne equipment, airborne equipment mounting rack work under severe mechanical vibration. To improve the system reliability, we established accurate parametric finite element model, obtained modal of frequency and vibration by analysis, confirmed correctness of this method by experiment, laid the foundation of its comprehensive dynamic analysis and structure optimization design for structure and working conditions of a electronic equipment mounting rack in this paper.
