Structural Dynamic Property Analysis of a Spaceborne Component

The structural dynamic properties of spaceborne electronic equipment are critical to the reliability and safety of the entire system. In this paper a spaceborne component is taken as the research object, a complete finite element model of a spaceborne component is established by ABAQUS and the modal analysis is conducted. According to the inherent dynamic characteristics of the structure, the structural response of the structure under the load of acceleration overload, sinusoidal vibration, random vibration and charging pressure is analyzed and the corresponding structural deformation and stress distribution are obtained. The analysis results show that the structural design of the component meets the design requirements of the spaceborne mechanical environment and provides a reliable basis for the structural design of component.
