Random Vibration Analysis for Electronic Equipment of an Airborne Radar

The airborne electronic equipment works under the complex vibration environment. Its reliability can be validated by random vibration analysis. In this paper the modal analysis is carried out first for the electronic equipment of an airborne radar by the finite element method and the vibration characteristic of the structure is obtained. Then the stress and deforming graphs of the structure are obtained by random vibration analysis. Finally, the stiffness and strength performance of the airborne electronic equipment are verified according to the analysis result. The results show that the strength and stiffness of the electronic equipment meet the design requirements and the reliability of the electronic equipment is validated.
